Updates from Customs & Border Protection (CBP): I-94 Numbers Will be Alphanumeric Starting May 2
Customs and Border Protection announced that as of May 2019, the 11-digit numerical format for I-94 numbers will be alphanumeric. CBP will have a completely new format with 9 digits, a letter in the 10th position and a digit in the 11th position. All unexpired I-94 records with the old numerical format will remain valid until the date that is listed on the paper I-94 record or on the online version found on the Customs and Border Protection I-94 website. Attorneys are instructed to inform their clients of the update to bypass any confusion.
