The number of stamps needed to send a letter to London depends on the weight of the letter and the postage rates set by your postal service. For example, in the United States, a standard first-class letter weighing up to 1 ounce typically requires one Forever stamp. However, if your letter is heavier or if you're using an international service, you may need additional stamps or a different postage option. It's best to check with your local postal service for the most accurate information.
