Using a P.O. box or a virtual address is a good idea for your LLC if you don’t have a brick and mortar business. A virtual mailbox will allow you access to your mail anytime of day thanks to its online presence, while a P.O. box will be restricted to certain post office business hours. Alternatively, you can also use your registered agent’s business address as your business address if you’d like to maintain your privacy or if you can’t use your home address for any reason.
