A virtual mailbox costs between $10 to $20 per month. Some plans start around $6 on the low end and range to $50 or more on the high end. The cost of your virtual mailbox depends on how it’s being used and the types of services you need. For example, if you just need a place for your mail to get delivered and scanned, it’s going to be much cheaper than a business mailroom package with a virtual office solution. Some virtual mailbox services, like package forwarding and check deposits, cost extra and get billed per use.
