How to Date Vintage Clothing by the Label: 8 Reliable Clues

To date vintage clothing, cross-check several clues from the label and the construction: whether there are care symbols or not, an address with or without a ZIP code, a union label, the country of manufacture, the fabric content, the type of zip and the finishing. Each clue gives an "earliest" or "latest" date. Combined, they place the piece within a decade, rarely a specific year.

You'll come away with eight clues ranked by reliability, a grid to cross-check them and the right way to mention them in your listing.

Why does dating a piece change its price?

Because vintage buyers pay for an era. A 1970s work jacket and a 2015 reissue can look alike in photos and not sell for the same price, or to the same audience.

Dating correctly also helps you avoid the opposite mistake: selling a 2000s piece as "80s vintage". A collector will spot it, and your credibility will take a hit. An honest range beats a made-up year.

Which label clues give you a date?

The most reliable clues are the ones based on a dated fact: a law, a standard, an event. The others are collectors' benchmarks, useful but to be handled with care.

The ZIP code on a US address

Five-digit ZIP codes were introduced in the United States on 1 July 1963, as Wikipedia notes. A label showing a US manufacturer's address with a ZIP code therefore dates from that year at the earliest. An address without a code, sometimes with just a zone number after the city, points to an earlier period without proving it.

The union label

Many American garments carry the label of the ILGWU, the International Ladies' Garment Workers' Union. This union merged in 1995 to form UNITE. An ILGWU label therefore places the piece before the mid-1990s. Collectors narrow the date further using variations in the label's design over the decades.

Care symbols

GINETEX, the organisation that standardised care symbols in Europe, was founded in 1963. In Canada, a first symbol standard dates from 1970. In the United States, the ASTM pictogram standard was published in 1996; before that, instructions were often written out in full. So an American piece with text only and a piece with pictograms are probably not from the same era.

A word of caution: symbols were adopted gradually and it depends on the country and the brand. The absence of symbols is only a clue.

Country of manufacture

Some countries date a piece on their own. "Made in West Germany" or "Made in W. Germany" points to manufacture before reunification in 1990. Other references to states that no longer exist under that name work the same way.

More generally, because textile production gradually moved offshore, "Made in USA", "Made in France" or "Made in UK" pieces from major brands are more common in earlier decades. It's a benchmark, not a rule.

The RN number

The RN is an identification number issued by the FTC, the US competition authority, to American businesses that manufacture, import or distribute textiles, according to the FTC. It lets you find the company behind the label using the FTC's public database. Collectors' tables link number ranges to periods when they were issued, but an old number can stay in use for years: it gives you an earliest date, not a manufacturing date.

What do the construction and fabrics tell you?

After the label, look at the piece itself. These clues are less precise, but they confirm or contradict what the label says.

The zip. Metal zips from older brands on pieces that would carry a nylon one today, or vice versa, show a trend. Note the brand engraved on the pull and look up its history.

The stitching. T-shirt collectors check whether the sleeve and bottom hems are single-stitched, common on older T-shirts, or double-stitched, which became standard later. It's a useful benchmark, but some recent T-shirts are single-stitched.

Fabric content. The widespread appearance of certain synthetic fibres, or on the contrary a 100% wool composition on a mass-produced piece, points to an era. Cross-check with the rest.

Brand labels. Many brands changed their logo, font or label colour over the decades. Collector communities document these changes brand by brand, and it's often the most precise clue for a well-known brand.

How should you mention it in your listing?

Give a range and show your evidence. "Vintage 80s jacket, union label and address with ZIP code shown in photos" is better than "vintage 1983 jacket" with no justification.

Put the word "vintage" and the decade in the title: those are terms buyers type. Our article on how to write a good Vinted title shows where to put them. In the description, add flat measurements: older sizes don't match today's sizes, and that's the number one cause of disappointed returns.

If you can't date it, just say so. "Older piece, era undetermined" is still more credible than a random date.

Is it worth the time?

On an €8 piece, no. On a piece from a sought-after brand where the decade changes the value, yes, by a long way.

The problem comes afterwards. You spend twenty minutes dating a jacket, buy it for €10 and sell it for €60. Nice margin. But over the whole month, between vintage pieces carefully dated and pieces bought on a hunch that stay in stock, you don't really know what your vintage rail earns. The time spent researching doesn't show up anywhere.

Tracking what each piece cost you and what it brought in is what tells you whether your thrifting eye is profitable. Revendor syncs your Vinted sales with your stock and calculates your profit item by item.

Where should you start if you're new to vintage?

Start with a single brand you come across often. Learn its labels decade by decade. Within a few weeks, you'll date its pieces at a glance, and that knowledge then transfers to other brands.

Keep a folder of photos of labels you've dated with certainty. It's your reference library, and it's worth more than any table found online.
