Can i add another stamp to metered mail

In general, it is not possible to add another stamp to metered mail. Here's why:

1. Metered mail is pre-paid: When you use a postage meter, you're essentially pre-paying for the postage. The meter prints the postage directly onto the envelope or package, and the amount is deducted from your postage account.
2. No additional postage allowed: The USPS (United States Postal Service) regulations prohibit adding additional postage to metered mail. This is because the postage meter is designed to provide a fixed amount of postage, and adding more postage could create confusion and potential errors.
3. Voiding the metered postage: If you try to add another stamp to metered mail, it could void the original postage. The USPS may not accept the mail for delivery, and you may be required to pay additional postage or re-mail the item.

However, there are some exceptions and alternatives:

1. Additional postage for oversized or heavy items: If you need to send an oversized or heavy item, you may need to add additional postage. In this case, you can use a separate stamp or a postage label to cover the additional cost.
2. Postage due: If the recipient is not present to accept the mail, the USPS may leave a "postage due" notice. In this case, the recipient can pay the additional postage due at a post office.
3. Re-mailing: If you need to send an item with additional postage, you can re-mail it using a new envelope or package with the correct postage.

In summary, it's generally not possible to add another stamp to metered mail. If you need to send an item with additional postage, you should use a separate stamp or postage label, or re-mail the item with the correct postage.
