Whether you're designing an online form or a mobile site, it's important to know what is address line 2. If your site requires users to input their address, it's important to ensure that the data collected is accurate. Incorrect input can cause validation errors.
The USPS requires that addresses be validated, so you need to make sure that you're processing data correctly. Incorrect addresses can be complex to parse and may be difficult for automated processing systems to handle.
Address line 2 can be an effective way to ensure that your data is clean, but it's also easy for it to become a source of confusion. Adding too much information to the field can lead to complicated parsing and resulting in invalid addresses.
Using an advanced address validation tool can ensure that your addresses are standardized and easy to parse. It can also fix addresses that are improperly structured. You can use PostGrid's Address Validation API to help you validate addresses. It can also help you validate address line 2 variations.
In most cases, you don't need to use a second address line. However, if your form requires users to enter address information, it's important to make sure the information is clean and easy to enter. Address Line 2 is also a good place to provide special instructions, landmarks, and C/O addresses.
Address line 2 can also be a place for billing addresses. If you're shipping items, you may need to provide multiple ship addresses.
