Can you mail a letter with a 20 cent stamp

In the United States, the United States Postal Service (USPS) has a postage rate chart that outlines the cost of mailing a letter based on its weight and size.

As of 2022, the USPS rates for mailing a letter are as follows:

• First-Class Mail Letter (1 oz): $0.60
• First-Class Mail Letter (2 oz): $0.74
• First-Class Mail Letter (3 oz): $0.88

Since a 20-cent stamp is equivalent to $0.20, it is not enough to mail a letter in the United States. You would need to purchase additional stamps or use a more expensive postage option to ensure your letter is properly mailed.

However, it's worth noting that some countries have lower postage rates, so it's possible that a 20-cent stamp could be sufficient for mailing a letter internationally. But for domestic mail in the United States, you would need to use a stamp with a value of at least $0.60 to mail a standard letter.

It's always a good idea to check the USPS website or consult with a postal worker if you're unsure about the correct postage for your mail.
