What envelope to use for certified mail

For certified mail, you'll need to use a special type of envelope that's approved by the United States Postal Service (USPS). Here are the requirements:

1. Certified Mail Envelope: You'll need to use a certified mail envelope that's specifically designed for certified mail. These envelopes are usually white or light-colored and have a distinctive design.
2. Size: The envelope should be a standard size, either #6 3/4 (3.5 x 6.125 inches) or #9 (4.125 x 9.5 inches).
3. Window: The envelope should have a clear plastic window that allows the recipient to see the contents without opening the envelope.
4. Addressing: The envelope should be addressed to the recipient with their name and address in the correct format.
5. Certified Mail Label: You'll need to affix a certified mail label to the envelope, which includes the following information:
   • The sender's name and address
   • The recipient's name and address
   • The date of mailing
   • The tracking number (also known as the "tracking label")
   • The certification number (also known as the "certified mail number")

You can purchase certified mail envelopes and labels at your local post office or online from the USPS website.

Here are some tips to keep in mind:

• Make sure to use the correct postage and affix it to the envelope.
• Fill out the certified mail label carefully and accurately.
• Keep a copy of the certified mail label and the tracking number for your records.
• The recipient will need to sign for the certified mail when they receive it, which provides proof of delivery.

By following these guidelines, you'll be able to send certified mail using the correct envelope and ensure that your mail is properly tracked and delivered.
