Are carrier and travel service providers required to verify that an individual traveler is authorized to travel to Cuba?
OFAC's answer
Persons subject to U.S. jurisdiction providing authorized carrier or travel services must retain for at least five years from the date of the transaction a certification from each customer indicating the provision of the [CACR](https://www.ecfr.gov/cgi-bin/text-idx?SID=7ec37a7c0b7426c5484162ef82fd0c51&mc=true&tpl=/ecfrbrowse/Title31/31cfr515_main_02.tpl) that authorizes the person to travel to Cuba. In the case of a customer traveling under a specific license, a copy of the license or the license number must be maintained on file. The names and addresses of individual travelers must also be maintained on file for at least five years. See [31 CFR § 515.572](https://www.ecfr.gov/cgi-bin/text-idx?SID=f7b161e13b79bf0d3e97c36fa9bab947&mc=true&node=se31.3.515_1572&rgn=div8)(b). This information, including certifications and copies of licenses or license numbers, may be collected and maintained in any form, including electronically.
