ICE Online Detainee Locator System (ODLS)

The primary public tool for locating individuals is the ICE Online Detainee Locator System at locator.ice.gov.

Required Information

To search, you need either:

  • A-Number (Alien Registration Number) + Country of Birth, OR
  • Full biographical information: First name, last name, date of birth, country of birth

Critical Limitations

Issue Impact
8+ hour data lag Individuals may not appear for days after apprehension
No fuzzy matching Name must match exactly as entered by intake officer
Spelling variations Hyphenated names, maternal/paternal surname order may cause failures
Juveniles excluded No records for individuals under 18
Transfer gaps Records disappear during facility transfers

A-Number Format

The A-Number is a 9-digit identifier beginning with "A" (e.g., A012345678).

  • If you have an 8-digit number, add a leading zero
  • Find A-Numbers on: Work permits, green cards, I-797 USCIS receipts, prior court notices
