How to Check Levi’s Jeans Authenticity: Tags, Codes, Stitching & More
Buying a great pair of pre-owned Levi’s jeans can mean finding a classic fit and distinctive worn-in denim. It can also mean finding jeans with real character. But when shopping second-hand, one question often comes up: how can you tell if Levi’s jeans are real?
There is no single detail that should be used to authenticate every pair.
Levi’s has produced jeans for generations, and labels, tabs, materials, manufacturing locations and construction details have changed over time. Used jeans may also have faded, been altered or undergone repairs.
The best approach is therefore to examine several features together.
This guide covers the details worth checking when buying used Levi’s in the UK. These include the Red Tab, back patch, inside labels, PC9 product code, hardware and pocket stitching.
How Can You Tell If Levi’s Jeans Are Authentic?
To check whether a pair of Levi’s appears authentic, look for consistency across the entire garment.
Examine the Red Tab, Two Horse patch, care labels, product or style number, buttons, rivets, pocket stitching, fly and overall construction. The details should make sense together for the model and approximate age of the jeans.
A strange-looking label does not automatically mean a pair is counterfeit. Equally, having a Red Tab or Levi’s-branded button does not prove authenticity on its own.
For pre-owned denim, think of authentication as a series of checks rather than a single test.
Why Pre-Owned Levi’s Require More Than One Authenticity Check
A brand-new pair of jeans can be compared relatively easily with the current version sold by the manufacturer. Pre-owned Levi’s are more complicated.
Older jeans may have labels that are no longer used. A leather-style patch can fade or become almost unreadable. A Red Tab can become worn. Hems may have been shortened, and buttons, zips or sections of stitching may have been repaired.
Some genuine Levi’s were also produced in different factories and countries, while individual models may use different fabrics, flies and construction methods.
This is particularly important when buying vintage denim.
Rather than asking, “Does this pair have the correct label?”, a more useful question is: “Do all of these details make sense together?”
1. Check the Levi’s Red Tab
The small tab on the back pocket is one of the most recognisable features associated with Levi’s.
On many pairs, you will find a red fabric tab positioned along the edge of the right rear pocket. Depending on the product and production period, the design and lettering can vary.
Look at the Shape, Placement and Finish
Start by examining how the tab is attached.
It should look like an intentional part of the pocket construction, not something added later. Check the stitching around it and the shape of the tab. Its overall quality should match the rest of the jeans.
Poor printing, obviously incorrect typography or careless attachment can justify taking a closer look at the rest of the garment.
However, avoid using tiny differences in lettering as your only authentication method. Genuine Levi’s tabs have changed over the years.
Does a Blank Levi’s Tab Mean the Jeans Are Fake?
No.
One of the most useful details for second-hand buyers to know is that genuine Levi’s can have a blank tab.
A blank tab may retain the familiar shape but not display the Levi’s name in the way shoppers expect. It is an intentional variation used on genuine products.
That means a blank Red Tab should not automatically be treated as a counterfeit warning sign.
Check the rest of the jeans before making a judgement.
Big E vs Small e Levi’s Tabs
People researching vintage Levi’s often look at whether the tab uses an uppercase or lowercase “E”.
Changes in Levi’s tab branding can help estimate the era of some older garments. This is why vintage denim collectors often discuss the distinction.
But the tab should still be considered alongside other features.
If a seller claims a pair is an older vintage model, check whether the main details agree. The tab, labels, hardware, patch and construction should tell a consistent story.
2. Inspect the Levi’s Back Patch
The back waistband patch is another useful place to look.
Many classic Levi’s jeans feature the famous Two Horse design, alongside information connected with the style and size.
On used jeans, however, the patch may look very different from one that has just left the shop.
Check the Design and Typography
Look at the overall quality rather than expecting every patch to be identical.
The illustration, lettering, spacing and printed information should appear deliberate and consistent. Very crude artwork, obvious spelling errors or badly proportioned branding may warrant further investigation.
Remember that different Levi’s ranges and production periods can use different patch materials and designs.
Compare the Size Information
Where the patch displays waist or length information, compare it with the inside labels and the actual garment.
A mismatch is not automatically evidence of a counterfeit pair. Second-hand jeans may have been altered, labels can fade and vintage sizing is not always directly comparable with modern sizing.
But unexplained contradictions are worth checking.
A Worn Patch Can Still Be Genuine
A heavily washed pair of Levi’s might have a cracked, faded or partly missing patch.
That can be completely normal.
In fact, condition is one of the reasons authenticating used denim is different from checking new clothing. Wear that looks unusual on a new pair can be expected on jeans that have been worn for years.
3. Check the Inside Care Label and Levi’s Style Code
The inside labels can provide some of the most useful information on modern Levi’s.
Look through the wash and care labels sewn inside the jeans and check for product-identification information.
What Is a Levi’s PC9 Code?
On many modern Levi’s products, you can find a PC9 product code.
A typical format looks similar to:
00505-4886
The first five digits identify the product style, while the final four digits identify a particular finish or wash.
For example, the first portion of a code can correspond with a style such as the Levi’s 505.
This gives second-hand shoppers something useful to cross-check against the jeans they are considering.
Compare the Style Code With the Jeans
If the label identifies a particular model, the physical jeans should broadly correspond with that model.
Consider the fit, fly, cut and other major features.
A label identifying one type of jeans attached to a garment that clearly resembles an entirely different model would justify closer inspection.
At the same time, do not expect every older pair to follow the labelling conventions used today.
What If Vintage Levi’s Have Different Labels?
Vintage Levi’s can contain very different internal labels from current products.
Care-label regulations, manufacturing systems and branding have all evolved. Some older garments therefore will not have the same modern PC9 presentation that you may find on newer jeans.
For a genuinely older pair, judge authenticity against the period in which it was supposedly produced. Modern rules may not apply.
Applying modern rules to every vintage pair can lead to genuine garments being incorrectly dismissed as fake.
4. Examine the Buttons and Rivets
Hardware is another useful piece of the puzzle.
Levi’s jeans are closely associated with riveted construction, and many models feature branded metal buttons.
Check the Waist Button
Look closely at the main waistband button.
Branding should appear clean and intentional, and the quality of the metalwork should be consistent with the rest of the jeans.
A button that looks noticeably cheaper than every other component can be a reason to investigate further.
But remember that buttons can be replaced.
A genuine pair of jeans that has been repaired during its lifetime may no longer have every piece of original hardware.
Look at the Reverse of the Button
The reverse side of the top button can also contain stamped manufacturing information.
This detail is frequently checked by collectors when examining Levi’s.
Treat it as supporting evidence rather than a standalone authentication code. Production systems have changed and different generations of Levi’s should not necessarily be expected to carry identical markings.
Inspect the Rivets
Look at the rivets around the front pockets and compare them with one another.
The finish, embossing and installation should generally look consistent.
Once again, age matters. Oxidation, scratching and surface wear can be perfectly normal on pre-owned jeans.
5. Look at the Back-Pocket Stitching
Levi’s curved back-pocket stitching is one of the brand’s most recognisable design features.
Examine both rear pockets and look at the overall shape and symmetry of the stitching.
On a modern pair in good condition, sloppy or inconsistent pocket stitching deserves attention. Inspect the other details more carefully.
On older jeans, things become less straightforward.
Stitching can fade, break or be partially removed through years of wear. A damaged pocket may also have been repaired by a previous owner.
The presence or condition of the arcuate-style stitching should therefore be considered alongside the rest of the garment.
6. Check the Fly, Seams and General Construction
One of the easiest mistakes when checking Levi’s authenticity is assuming every model should be constructed like a 501.
They are not.
Button Fly or Zip Fly?
The classic Levi’s 501 Original is strongly associated with its button fly.
Other Levi’s models can use zip flies.
This makes the model number important. A zip fly is not a general indication that Levi’s are fake; it simply needs to make sense for the particular style.
When examining used jeans, compare the claimed model with the construction of the garment.
Examine the Seams
Turn the jeans inside out if photographs or access allow.
Look at the seam construction, pocket bags, thread consistency and finishing. Good-quality construction should generally look deliberate rather than rushed.
A few loose threads on well-worn second-hand jeans are completely different from badly assembled seams throughout an otherwise supposedly new-looking garment.
Context matters.
Check the Hems
Pre-owned jeans are frequently altered.
A pair may have been shortened, lengthened, tapered or repaired by a previous owner. Original hems may have been removed entirely.
Alterations affect originality and potentially value, but they do not necessarily affect authenticity.
That distinction is especially important when shopping for used denim.
7. Check the Denim and Fabric
Fabric can provide useful supporting clues, but it should never be the only test.
Depending on the model, period and specific product, Levi’s can be made from rigid cotton denim or fabric containing stretch fibres.
Modern examples of the same famous fit can even be available in more than one fabric composition.
That means statements such as “real Levi’s are always 100% cotton” are too simplistic.
Check whether the fabric makes sense for the exact model, product code and approximate production period.
Are All Genuine Levi’s Selvedge?
No.
Selvedge denim is desirable among some denim enthusiasts. However, most genuine Levi’s jeans should not be expected to have a selvedge edge.
Levi’s has produced both selvedge and non-selvedge denim.
The absence of selvedge therefore does not mean a pair is fake.
8. Genuine Levi’s Can Have Repairs and Alterations
This is one of the most important points when buying pre-owned jeans.
Authenticity and originality are not the same thing.
A pair can be genuine Levi’s but no longer entirely original.
Authentic jeans may have been professionally shortened or patched at the knee. They may also have crotch repairs, repaired back pockets or replacement hardware.
For buyers, the key question is whether these alterations were disclosed. Also consider whether they affect the fit, appearance or value.
Visible repairs can even form part of the appeal of well-worn denim.
When shopping online, clear photographs and accurate condition descriptions are therefore just as important as the brand label.
9. How to Check Vintage Levi’s
Authenticating vintage Levi’s requires more care than checking a recent pair.
Features such as tabs, care labels, patch designs, hardware and manufacturing techniques changed across different periods. A detail that looks unusual by today's standards may be completely appropriate for an older garment.
Start with the seller's claimed era.
Then consider whether the different components of the jeans are compatible with that period.
For example, do the labels look plausible for their age? Does the degree of wear make sense? Do the tab, hardware and construction appear consistent with one another?
Be particularly cautious when a very specific or unusually early production date is being used to justify a high price.
The more valuable the claimed vintage pair, the more important detailed authentication becomes.
For rare or highly collectible Levi’s, a specialist vintage denim assessment may be more appropriate than relying on a general online checklist.
10. Red Flags When Buying Used Levi’s Online
Most authenticity checks are about finding inconsistencies rather than spotting one magical sign of a fake.
Potential warning signs include obvious spelling or branding errors. A product code may also conflict with the claimed item. Poor construction throughout the garment is another concern. Contradictory labels or missing detail photos also deserve caution.
Price can also provide context.
A surprisingly low price does not automatically mean a pair is counterfeit. Excellent second-hand bargains certainly exist. However, an unusually cheap listing for a supposedly rare vintage model deserves closer inspection.
Condition should be evaluated separately.
Fading, fraying, a worn patch or repaired stitching can all be completely normal on genuine pre-owned jeans.
What Photos Should You Check Before Buying Pre-Owned Levi’s?
When buying Levi’s online, detailed photographs can make a major difference.
Ideally, you should be able to see the front and back of the jeans. Check the Red Tab, back patch and full inside labels. Also inspect the product code, waistband button, hardware, fly, pocket stitching and hems. Any repaired or altered areas should be shown clearly.
For vintage or more expensive pairs, close-up photographs become even more important.
At Rewearable UK, detailed product information helps shoppers assess the branding. It also shows the condition and individual character of each pre-owned pair.
Buying Pre-Owned Levi’s in the UK: Check the Fit as Well as Authenticity
Finding genuine Levi’s is only half the job.
You also want a pair that fits.
When buying second-hand jeans, do not rely entirely on the size printed on the patch.
Denim can shrink, stretch and change shape through years of washing and wear. Previous owners may also have altered the waist or leg length.
For this reason, actual garment measurements can be particularly valuable when shopping pre-owned.
Compare the measurements of the jeans with a pair you already own and like.
Pay attention to the waist, rise, inside leg, thigh and leg opening where available. This can give you a more realistic idea of how the jeans will fit than the label alone.
Why Buy Pre-Owned Levi’s?
Levi’s jeans are particularly well suited to the second-hand market.
Denim often develops more character as it ages, with fades and wear patterns that cannot be reproduced exactly on a new garment.
Buying pre-owned can give shoppers access to discontinued washes and older fits. Individual pairs can also look different from current high-street stock.
And by keeping existing clothing in use for longer, resale gives garments another opportunity to be worn rather than immediately replaced.
For many buyers, the result is the best part of second-hand shopping: finding a pair that already feels unique.
Shop Pre-Owned Levi’s With Confidence
A good pair of used Levi’s should be assessed as a complete garment.
Instead of focusing entirely on a Red Tab, button or patch, compare the branding, labels, construction, style information and condition.
Minor wear can be normal. Repairs may simply show that somebody thought the jeans were worth keeping. Vintage labels may differ considerably from modern ones.
What matters most is whether the details are consistent with each other and with the Levi’s model being sold.
If you are searching for your next pair, explore the pre-owned Levi’s available from Rewearable UK. Check the photographs, measurements and condition information before choosing the pair that suits you.
Levi’s Authenticity Checklist
Before buying a used pair, check:
- Red Tab: Does its shape, placement and construction look consistent? Remember that genuine blank tabs exist.
- Back patch: Check the design, printed information and condition.
- Inside labels: Look for coherent branding and product information.
- PC9/style code: On many modern products, compare the style code with the claimed model and finish.
- Buttons and rivets: Inspect their quality, markings and consistency while allowing for possible repairs.
- Back-pocket stitching: Check the distinctive curved stitching and overall workmanship.
- Fly: Confirm that a button or zip fly is appropriate for the model.
- Fabric: Make sure the composition makes sense for the particular style and production period.
- Hems and alterations: Identify any shortening, repairs or replacement components.
- Overall consistency: Never make an authenticity judgement from one detail alone.
Frequently Asked Questions About Levi’s Authenticity
How can I tell if Levi’s jeans are real?
Check several details together, including the Red Tab, back patch, care labels, product or style code, hardware, stitching, fly and overall construction. Authenticity is best assessed through consistency across the entire garment rather than one feature.
Do all real Levi’s have a Red Tab?
Do not use the presence of a standard branded Red Tab as the only test. Levi’s has produced different tab designs and variations across products and periods.
Can genuine Levi’s have a blank Red Tab?
Yes. Genuine Levi’s products can feature a blank tab without the usual Levi’s lettering. A blank tab alone is not a sign that the jeans are counterfeit.
Where is the style number on Levi’s jeans?
On many modern Levi’s products, the style or PC9 code appears on the internal wash and care labels.
What does a Levi’s PC9 number mean?
A modern PC9 code typically identifies both the product style and the particular finish. The first five digits identify the style, while the final four identify the finish or wash.
Do Levi’s 501 jeans have a button fly?
The classic 501 Original is known for its button fly. Other Levi’s models can have zip flies. Always compare the fly with the specific style instead of using it as a universal authenticity test.
How can I tell if vintage Levi’s are genuine?
Evaluate the garment according to its claimed production period. Look at the tab, labels, patch, hardware, stitching and construction together, remembering that older Levi’s may differ considerably from current products.
Does a damaged back patch mean Levi’s are fake?
No. Back patches can fade, crack or become damaged after repeated washing and years of wear. This is particularly common with pre-owned and vintage jeans.
Can authentic Levi’s have replacement buttons or repairs?
Yes. Genuine second-hand jeans can have replacement hardware, repaired pockets, patched denim or altered hems. These changes may affect originality or value, but they do not automatically mean the jeans themselves are counterfeit.
Are all authentic Levi’s made in the same country?
No. Genuine Levi’s have been manufactured in different countries. Country of origin should be considered as one part of the garment's overall production information, not as a standalone authenticity test.
Are all genuine Levi’s 100% cotton?
No. While many classic Levi’s are made from 100% cotton denim, other genuine products include stretch fibres. Fabric composition varies according to model, finish and production period.
What should I check before buying Levi’s online?
Look closely at photographs of the Red Tab, back patch, internal labels, product code, hardware, fly, pockets and hems. Also check measurements and any disclosed repairs or alterations, especially when buying pre-owned jeans.
Final Thoughts
Learning how to check Levi’s jeans authenticity is not about memorising one secret feature. It is about understanding how different details work together.
The Red Tab matters, but so do the labels. The style number matters, but so does the construction. Hardware can provide clues, but repairs are common on jeans that have had a long life.
When buying pre-owned Levi’s in the UK, consider the full garment. Check the condition and measurements carefully. Focus on contradictions rather than normal signs of age.
That approach also makes second-hand Levi’s easier to appreciate. Distinctive denim and individual wear can give an older pair real character.
