Do you need to send a letter to San Diego in the United States? Or a parcel? Then, your best option is to send it through USPS. In general, this is the cheapest service that you will find. It is quite efficient too. You get the best value for your money.
However, when you write the destination address, do not forget to include the zip code. This is a number consisting of five digits. Why is it so important to add the right San Diego zip code? Well, without it, your letter or parcel will take much longer to get to its destination. Or it may never make it.
This number started to be used in the United States in 1963. Initially, it was a number with five digits only. Twenty years later, the USPS added four more digits to identify more specific areas. This format is known as ZIP+4. The most commonly used codes are the numbers with five digits.
Do Not Use the Wrong Code
When you forget to write the zip code of the destination on the envelope, the letter will be sent back to you. The same will happen if you write an invalid number. However, if you write the wrong number, but which is valid, the letter will go to the post office of that code. When the postman will try to deliver the letter, they will notice that the address does not exist in that area. So, the letter will be sent back to the post office it came from. Then, any of the following two things can happen:
- The letter will be sent back to you. This is the most likely thing to happen;
- Employers will try to figure out the right code using the address that you wrote. Then, they will reroute it to the right post office. However, this is unlikely to happen. As you can imagine, there are thousands of letters to sort every day in a post office. Employers do not have the time to read the address of a letter in particular.
The main function of this code is to automate the sorting of letters. It is much easier to scan a barcode than to read the entire address. In a large American city, there may be hundreds of thousands of letters to sort in a single day.
