Carpet Certificates Explained: How to Verify a Certificate of Authenticity
Almost every carpet seller offers a "certificate". Some are detailed, verifiable documents tied to one individual carpet. Others are generic printouts that could accompany any rug in the shop. Knowing the difference protects you when you buy, insure, sell or repair a handmade carpet.
In short: a carpet certificate is only as reliable as two things: who issued it, and whether it can be matched to one specific carpet. A trustworthy certificate names a registered issuer, shows the carpet's photograph and measured specifications, carries a unique identifier you can look up, and is signed and sealed. Every handmade carpet sold by Azimzadeh comes with a certificate that meets each of these points.
The documents that can come with a carpet
"Certificate" is used loosely. These are the documents you are most likely to meet, and what each one actually establishes:
| Document | What it establishes | What it does not establish |
|---|---|---|
| Seller's certificate of authenticity | The seller's written statement of what the carpet is: its type, origin, materials, dimensions and density. | It is only as strong as the seller behind it. It is not an independent appraisal. |
| Tax invoice | Who sold the carpet, to whom, when and for how much. | A full technical description of the carpet, unless the invoice includes one. |
| Product identifier (GTIN) | A unique number registered through GS1 that links the carpet to the company that registered it and to its registered data. | GS1 does not inspect, grade or value the carpet. |
| Woven signature | The name of a workshop, designer or city woven into the carpet, which supports identification. | On its own, it is not proof of authenticity or that the named master personally wove the piece. |
| Formal valuation | A valuer's opinion of value for a stated purpose, such as insurance. | It is a separate exercise from a certificate, and a value for one purpose does not guarantee a future price. |
A good certificate works together with the invoice: the certificate says what the carpet is, the invoice says that you bought it, and the identifier connects both to the physical piece.
Five marks of a trustworthy certificate
- A named, registered issuer. The certificate should state the company that issues it, with an address you can contact. An anonymous "certificate of authenticity" with no issuer is worth very little.
- A photograph of the actual carpet. Not a stock image or a drawing of the design.
- Specific, measured details. Measured dimensions and area; the pile and warp named separately; knot density in a stated unit; weight measured rather than estimated. "Persian, wool and silk" identifies nothing.
- A unique identifier. A product code or GTIN that belongs to this carpet alone, so the document cannot simply be reused for another piece.
- Signature, stamp and seal. Physical marks that make the original document difficult to copy convincingly.

How to verify an Azimzadeh certificate
Every handmade carpet we sell receives an Azimzadeh Certificate of Authenticity, with no issuance fee. To check one:
- Check the embossed seal. The certificate states that it is not valid without the embossed seal. Look for it alongside the official signature and stamp.
- Compare the photograph and dimensions with the carpet. The photograph, design and measured dimensions should match the piece in front of you.
- Tap the NFC cover. The certificate cover contains an NFC chip. Tap it with a compatible phone and it opens the carpet's product information page.
- Look up the product identifier. Each carpet is registered through GS1, the global product identification system, and its identifier (GTIN) is printed on the certificate. The enclosed guidance card explains how to look it up. A GS1 lookup can confirm that the GTIN is valid, which company it is licensed to, and whether basic product information has been registered for it.
- Check it against your invoice. The purchaser's name and the carpet's identifier should be consistent across both documents.
Be clear about what the GS1 step means. GS1 provides product identification and lookup of the registered data; it is not an independent GS1 appraisal of the carpet's materials, age or value. The authenticity certificate itself is issued by Azimzadeh, and it is our statement about the carpet we sold you.
Warning signs on any certificate
- No photograph, or a photograph that does not match the carpet.
- Vague materials such as "wool and silk" without saying which part is which, or "silk" for a fibre that may be viscose. See kork, silk and viscose explained.
- A raj figure in a knots per dm² field. The two units measure different things; our guide to raj explains why the numbers differ.
- A certificate that claims to be an independent valuation, or that uses a lookup service's name as if that organisation had inspected the carpet.
- A promise of future value. A certificate records what a carpet is. It cannot promise what it will be worth.
- A photocopy, a blank template or a photo of a signature offered instead of the issued original.
- An issuer you cannot contact. If the company on the certificate cannot be found, the document cannot be confirmed.
Certificates and older carpets
For an older or collectible carpet, a certificate should give a documented age or a clearly qualified estimate. The word "antique" is used differently in different markets and is not a substitute for stating the age. Browse our antique handmade rugs and old handmade rugs.
Keep your certificate safe
Store the original certificate with the invoice. If you ever insure, sell, clean or repair the carpet, the two documents and the product identifier make it easy to confirm that the paperwork belongs to that piece. If you send the carpet for cleaning or repair, keep the certificate at home and share a photograph of it instead.
Frequently asked questions
Does every Azimzadeh handmade carpet come with a certificate?
Yes. Every handmade carpet sold by Azimzadeh receives a Certificate of Authenticity with no issuance fee. It is sent to the address you give us once your purchase and invoice are finalised.
How can I check that a carpet certificate is genuine?
Check that it names a registered issuer, shows a photograph and measured details of the actual carpet, carries a unique identifier, and is signed and sealed. On an Azimzadeh certificate, you can also tap the NFC cover to open the carpet's information page and look up its GS1 product identifier.
Does GS1 certify or value the carpet?
No. GS1 provides the product identifier and lookup of registered data. It does not inspect, grade or value the carpet. The certificate of authenticity is issued by Azimzadeh.
Is a woven signature proof that a carpet is authentic?
No. A woven signature supports identification, but on its own it is not proof of authenticity or that the named master personally wove the carpet.
Is a certificate of authenticity the same as a valuation?
No. A certificate records what the carpet is. A formal valuation is a separate opinion of value for a specific purpose, such as insurance.
What should I do if I lose my certificate?
Contact us with your invoice and the carpet's product code. Keeping a photograph of the certificate with your records makes this easier.
