Every Slovakia detector in detail
Birth number (rodné číslo, also social security)
A national identity number. Validation: an embedded birth date and, for 10 digits, divisibility by 11. A run of digits with no separator is judged by words nearby; the detector's own keywords include birth number, id no, id number, identity number. Valid example: 856215/1235; the same shape that fails is 856215/1230.
IBAN
A bank account identifier. Validation: the registered length for the country and the ISO 13616 modulus 97 check. Valid example: SK31 1200 0000 1987 4263 7541; the same shape that fails is SK31 1200 0000 1987 4263 7540.
Phone number
A telephone number in the national format. Validation: between 7 and 15 digits, the range an international number can have. Valid example: +421 912 345 678.
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, psc. Valid example: 811 01.
Local-language context words for Slovakia
These are the words in the catalogue that confirm a value as belonging to this country's detector. Shared English words such as ID number or tax id are left out here because many packs use them; a word below points at this pack even when other packs are on.

birth number,r.č.,rodne cislo,rodné číslo,rč - Postal code:
psc,psč
How Maskflare masks Slovakia 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 Slovakia is a primary country.
- Monitor first: alert (counted, forwarded unchanged) when Slovakia is a primary country.
Compliance profiles that include the Slovakia 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 Slovakia identifiers.
