Whether a tax ID is required depends on the issuer’s country of registration and the tier of account limit you are applying for — not on the USDT card product category itself. Most readers are concerned about the “low-limit everyday spending” scenario. In that case, the vast majority of non-US and non-Canadian issuers only need a government ID. However, once you want to unlock higher monthly limits, or if the issuer is registered in North America or the EU, a tax ID is almost unavoidable.
US Issuers: SSN Is the Default Requirement
Issuers registered in the United States (such as Coinbase Card and the US version of Crypto.com Visa) almost universally require an SSN (Social Security Number) to complete advanced KYC. This is not issuers making things difficult — it is a mandatory requirement from FinCEN and the IRS for payment-type financial accounts. Any institution providing quasi-banking services within the US must report customer information that meets the threshold to the IRS.
Some issuers accept an ITIN (Individual Taxpayer Identification Number), which applies to non-citizens who have tax obligations in the US but do not hold an SSN. However, cards opened with an ITIN typically have weaker features: lower limits, restricted cross-border transfers, and exclusion from some cashback programs.
Canada and the EU: Different Requirements
Canadian issuers require a SIN (Social Insurance Number), for reasons similar to the US, driven by the CRA (Canada Revenue Agency).
After the EU’s MiCA framework took effect, high-value applications for crypto-related payment accounts require “proof of tax residency” — this is not necessarily a single tax ID field, but rather a combination of country of tax residence, local tax number, and address proof. Low-limit accounts (typically those with monthly spending below €1,000) can still go through simplified KYC. Specific rules vary by member state; see /compliance/eu for details.
Asia and Latin America: Government ID Is Primary
Issuers in Hong Kong, Singapore, Japan, South Korea, Southeast Asia, Brazil, Mexico, and similar markets generally only require a government ID or passport, selfie, and address proof for basic KYC. The tax ID field is either absent or marked as optional. This is why many Asia-Pacific users prefer Asia-route cards — the process is shorter and card rejection rates are lower.
Notable exceptions: Japan and South Korea have stricter real-name account binding requirements, but these are requirements at the identity verification level, not necessarily at the tax ID level. See /compliance/jp and /best/for-korea for detailed differences.
Comparison by Issuer Registration Country
| Issuer Country | Basic KYC | Advanced KYC |
|---|---|---|
| United States | Government ID + address | SSN or ITIN |
| Canada | Government ID + address | SIN |
| EU (MiCA) | Government ID + address | Proof of tax residency + local tax number |
| Hong Kong / Singapore | Government ID / passport | Proof of income (optional) |
| Latin America | Government ID | CPF (Brazil) / RFC (Mexico) |

Editorial Recommendation
Do: Choose a card whose issuer country matches your actual tax residency — US residents should look at Coinbase Card, while Asia-Pacific residents should prioritize Asia-route cards. Don’t: Avoid seeking out “zero-KYC offshore cards” to sidestep tax ID requirements. These products carry significantly higher risks of exit scams and account freezes compared to compliant options.
