Every Bulgaria detector in detail
Personal number (EGN, also social security)
A national identity number. Validation: an embedded birth date (with month offsets for the century) and a weighted modulus 11 check digit. A run of digits with no separator is judged by words nearby; the detector's own keywords include egn, id no, id number, identity number. Valid example: 7523169263; the same shape that fails is 7523169260.
IBAN
A bank account identifier. Validation: the registered length for the country and the ISO 13616 modulus 97 check. Valid example: BG80 BNBG 9661 1020 3456 78; the same shape that fails is BG80 BNBG 9661 1020 3456 70.
Phone number
A telephone number in the national format. Validation: between 7 and 15 digits, the range an international number can have. Valid example: +359 2 123 4567.
Postal code
A postal code, which identifies a place rather than a person on its own. Validation: the pattern only, with no checksum or structural validator. It needs one of 8 keywords within 48 characters before the value, such as post code, postal code, postcode, postenski kod. Valid example: 1000.

How Maskflare masks Bulgaria identifiers
Detections are replaced with a token such as mf_mask_d7e0 before the request goes to the AI provider, and with response restoration turned on the real value is put back in the answer. The other actions are redact, partial, hash, format-preserving encryption, generalize, alert and block.
- Protect now, Finance - Protect now, Healthcare and Developer: mask (a reversible token) when Bulgaria is a primary country.
- Monitor first: alert (counted, forwarded unchanged) when Bulgaria is a primary country.
Compliance profiles that include the Bulgaria pack: GDPR - EU/EEA.
Limits worth knowing
- A passing checksum shows that a value is well formed, not that it was issued to a real person. The examples on this page pass for that reason and are not real.
- 1 of the 4 detectors here matches on pattern alone (Postal code), so it can match text that merely has the same shape.
- Detectors read the text of the request. A value inside an image is found only after OCR, and a value split across lines is not one match.
- Names, addresses and free-text details are handled by other packs. This page is limited to the Bulgaria identifiers.
