What does co mean on mail
In the context of mail, "CO" is an abbreviation that stands for "Certified Official". It's often used to indicate that a document or package has been certified as official or authentic by a government agency, court, or other authorized entity.
Here are a few possible scenarios where you might see "CO" on a mail piece:
- Certified Official Mail: This is a type of mail service offered by the United States Postal Service (USPS) that provides proof of mailing and delivery. When you use Certified Official Mail, the USPS will provide a receipt and a tracking number, and the recipient will sign for the package upon delivery.
- Court-Ordered Mail: In some cases, a court may order a party to send a document or package to another party, and the mail piece may be marked "CO" to indicate that it's a court-ordered document.
- Government Agency Mail: Government agencies, such as the Internal Revenue Service (IRS) or the Social Security Administration (SSA), may use "CO" to indicate that a document or package is official and has been sent on behalf of the agency.
In general, "CO" on a mail piece indicates that the document or package is official, authentic, and has been sent with a specific purpose or authority.
