What slim.io detects

US Social Security Number. Pattern matching with contextual confidence scoring. Well-known test and placeholder values, like this example, are still reported, at low confidence and marked as test values, rather than silently dropped.

Canadian Social Insurance Number. The Luhn checksum raises or lowers confidence.

Visa, Mastercard, Amex, Discover, Diners and JCB number formats. The Luhn checksum raises or lowers confidence: a number that fails it can still be reported, at lower confidence. Numbers on slim.io’s list of published test cards can be dropped.

International Bank Account Number: a country code followed by the account digits, with mod-97 check-digit scoring.

Bank identifier codes used in international wire transfers. Matches both 8 and 11 character BIC formats.

US ABA routing number, detected next to a routing, ABA or transit label. The ABA check digit raises or lowers confidence.

US, Canadian and Dutch passport numbers, detected next to a passport label. UK, machine-readable-zone and generic formats are available but off in the default classifier settings.

A generic US format and all ten Canadian provincial formats, detected next to a licence label. Fifteen state-specific US formats are available but off in the default classifier settings.

Medical record numbers, detected with healthcare context such as an MRN label.

Medicare Beneficiary Identifier: the 11-character CMS format, written without dashes and next to an MBI or Medicare label.

Canadian provincial health card numbers in Ontario, Quebec, British Columbia, Manitoba and Saskatchewan formats, detected next to a label such as Health Card, OHIP, RAMQ or PHN.

Pattern matching on ASCII email addresses, including plus-addressing. Placeholder domains such as example.com are excluded.

North American phone numbers in nine format variants, with or without the +1 country code.

MM/DD/YYYY, YYYY-MM-DD and month-first written dates, detected next to a date-of-birth label.

First and last names, detected next to a label such as Name, Customer, Employee or Patient.

US street addresses next to an address label: house number, street name and suffix. Matching street addresses without a label is available but off in the default classifier settings.

IPv4 addresses.

Colon- or hyphen-separated 48-bit MAC addresses. This detector is available but off in the default classifier settings.
