Like a P.O. Box number, a private mailbox also includes a personal number for a mail operator to identify a mailbox.

A virtual business address should always include a private mailbox number, or PMB, that is unique to a renter.

A mail operator can identify and accept mail as long as it includes either the company name or authorized recipients verified in the account, plus the PMB number.

📌 Note: To ensure the mail you receive at your mail operator's space doesn't get returned to sender, include your PMB. Your mail operator may return mail without a proper address to the sender endorsed "Undeliverable as Addresses, Missing PMB or #Sign."
