Mailbox rental services in UK is a convenient way to get your mails at the right destination. But deciding which option to go for – PO Box or private mailbox can be tough.  Both have advantages but knowing the difference helps you choose the right one that actually helps you.

In the blog, we will be comparing the PO Box vs Private Mailbox services. The comparison will involve mailbox rates, safety and privacy features and more. A1 MailBox can provide a mailbox for your usage to mail your essential correspondence either on rent or for purchase.

What is a PO Box?

A post office box (also known as “PO Box”) is a box that is located in a post office to receive mail. In the UK, PO Boxes are operated by the Royal Mail. They are mostly used by a person or business wanting a secure place to receive mail.

Pros of a PO Box

  • Since your mail is secure in a post office, you won’t have to worry about mail theft.
  • One of the advantages of using a PO box is privacy, as it allows you to receive mail without disclosing your home address.
  • Most post offices have regular hours to give you access to your mail when you can easily manage it.

Cons of a PO Box

  • A PO Box can only be opened during the hours of the post office. You can only access your mail during these times.
  • PO Boxes don’t let you forward or receive your mail. Unlike private mailboxes, you can’t have your mail sent to you.
  • A PO Box is often limited in size, so it’s probably not suitable for larger packages.

What is a Private Mailbox?

A1 MailBox and similar private companies give you a private mailbox but Royal Mail do not. For people and businesses that want to rent a mailbox, these services offer a more complete solution.

Pros of a Private Mailbox

 

  • Your parcel and letter can be available for pickup any time you choose depending on service providers. A1 MailBox lets you pick up your mail whenever you like, at hours that suit you.
  • Private mailboxes offer the option of package forwarding to your home or another address, making them easier to work with than PO boxes.
  • Usually larger than PO Boxes, private mail boxes will enable their users to receive bigger parcels or packages.
  • You can have a private mailbox work as your professional mail address, a great option for indians or businesses which work from home.

Cons of a Private Mailbox

  • The cost to lease a private mailbox is often higher than that of a PO Box. This can be a downside for individuals on a budget.
  • Although you can find many places that offer private mailboxes, you will not be able to find them everywhere much like PO Boxes.
  • The government does not back private mailbox services which are provided by companies unlike PO Box service which is backed by the Royal mail. This may concern those who prefer public services.

PO Box vs Private Mailbox: What’s the Right Choice for You?

Whether to lease a PO Box or a private mailbox depends on needs and budgets. Let’s break down a few key factors.

  • Security and Privacy

Both PO Boxes and private mailboxes can keep your items secure. However, private mailboxes provide 24/7 access, and package forwarding, and other great features. Both options will work since you are worried about privacy.

  • Mailbox Rates

Renting a PO Box is usually cheaper than a private mailbox rental. If you’re concerned about the cost, a PO Box may be the cheaper alternative. However, however, if you require more services, for instance, package forwarding, then a private mailbox will yield extra value for you in the long run.

  • Accessibility

A private mailbox can help you access your mail outside of the hours when the post office is open. Businesses and individuals are busy almost all the time and do not have time to visit the post office. It is why services like A1 MailBox, offer access 24/7.

  • Size and Volume

People who receive lots of mail or large packages should use a private mailbox. Generally bigger than PO boxes, these boxes can take a larger quantity of mail. PO boxes may not be able to fit all your things, especially big ones.

  • Professional Image

Having a private mailbox will make their business look professional. If you run your business out of your home, you can use it as your business address. PO Boxes certainly keep things private but they don’t do a very good job at showing your business’ professional image.
