EMV Tag Lookup
Searchable reference of EMVCo data objects used in Books 3 and 4. Search by tag hex value (e.g. "5A", "9F26") or keyword (e.g. "PAN", "cryptogram", "CVM").
| Tag | Name | Description |
|---|
Data based on EMV 4.3 Book 3 (Application Specification) and Book 4 (Cardholder, Attendant, and Acquirer Interface). Tags marked with DF/FF prefixes are proprietary to specific payment schemes (Visa, Mastercard, etc.).
How to Use
Type a tag hex value directly (e.g. "5A" for PAN, "9F26" for Application Cryptogram) to find a specific data object. Or search by keyword (e.g. "cryptogram", "CVM", "issuer", "amount") to find related tags. The results filter in real-time as you type.

EMV Tag Reference
EMV tags are data elements defined in the EMV specification, identified by their tag values in TLV encoding. Each tag has a specific name, format, and length. Understanding tags is essential for debugging EMV transactions and developing terminal or card applications.
Frequently Used Tags
9F02 Amount Authorized (n12) - the transaction amount. 9F03 Amount Other (n12) - cashback amount. 9F27 CID (1 byte) - cryptogram type. 9F36 ATC (2 bytes) - application transaction counter. 9F37 Unpredictable Number (4 bytes) - terminal-generated random. 5F2A Transaction Currency Code (2 bytes, ISO 4217). 9F1A Terminal Country Code (2 bytes, ISO 3166). 9F4E Merchant Name (variable). 8E CVM List (variable). 9F38 PDOL (variable) - data the card requests from terminal. 9F5C Cumulative Total. 5F24 Application Expiry Date (YYMMDD). 9F07 Application File Locator (AFL). 9F10 Issuer Application Data - card-specific data for ARQC verification.
Tag Ranges
EMV tags follow ISO 7816 BER-TLV rules. 5F-prefixed tags (2-byte) are EMV-specific primitive data. 9F-prefixed tags (2-byte) are EMV transaction data. 6F and 7F are constructed templates. Tags in the A5 range are FCI proprietary data. BF tags are context-specific constructed objects. Use our EMV TLV Parser to decode full TLV data containing these tags.
Pair the Lookup with a Card to Inspect
Look up a tag from a dump you actually have, then verify on the same card.
