Receiving US Mail in México
It is possible to receive your U.S. mail without going across the border every week; there are several mail services in Rosarito that will do it for you. Their mailbox service offers you a P.O. Box for your mail and a street address for your FEDEX, UPS, etc. packages plus their Mexico street address in case you want all your mail in one place. They will also take your mail across.
They also offer Bank Errands and Postal Errands – Overnights, Priority Mail, Certified – most services for documents that you will find in the US Post office, as well as, UPS, FedEx, and DHL services.
Since the border policies are being enforced more strictly, they can no longer take packages across the USA. The “powers that be” tell them that it is against the law to “declare” for another person.
