Your (or Business) Name
5131 West Girard Avenue
Suite A PMB #03-12
Philadelphia, PA 19131-4403

How big is a PhillyBox Large Mailbox?

Our Large Mailbox interior measures 12" x 11.5" x 11", which is larger than USPS 'Large' Post Mail Box (11" x 11" x 11"), for 50% of the cost, and accepts more shippers - UPS, FedEx, DHL, Amazon and More! See the image at the top of this web page for an example of the amount and variety of packages you can fit in a PhillyBox! The door opening is 9.25" x 10.75", so any package measuring larger than the door opening will be automatically considered 'Oversize' and be stored securely indoors for pickup, as well as be subject to storage costs.

OK, challenge accepted - is there any package size restrictions?

As long as your package fits through our door (which measures 28" wide) we can accept it. Packages that don't fit through our door can be stored in the secured basement, which can accommodate larger packages but require a hand truck due to the steps. Management can accept extremely heavy packages as well, but any package over 200 lbs. will not be secured indoors and will require same-day pickup.

Can you accept packages that require signatures?

Yes, Management and Staff are over 21, so we can accept alcohol deliveries. However, we will require valid identification if the package requires you to be over 21 years of age, kids!

What types of ID do you accept during the application?

By law, we are required to see two forms of identification that include any two of the following (one must be a photo ID!) All ID's must be current (non-expired):

We will make photocopies of whatever you provide us, and store them securely for the duration of your business with us. Social security cards, credit cards, corporate IDs, and birth certificates are NOT acceptable forms of identification.

How often are my deliveries added to my Mailbox?

Shipments from the wide variety of shippers that we accept (UPS, FedEx, DHL, Amazon, USPS) unfortunately arrive at random times during the day, and cannot be reliably tracked. We require delivery people ring our bell with each delivery, and will notify you within minutes of the receipt of your package. This might happen multiple times a day, as we cannot 'group' photo notifications of packages.

Can I register my DBA / LLC / Non-Profit using this address?

Yes! Most business entities are required to register an official mailing address with the state, and that address is part of the public record. Once there, the marketing begins by snoopers tracking new business registrations - endless offers for high-interest credit cards and overpriced office supply catalogs. Plus, a business's use of an invalid address could result in legal problems, like the loss of limited liability protection. A PhillyBox used in association with our Open & Scan Services and Virtual Mailbox services, you could enjoy the credibility of operating your Small Business in West Philadelphia, but enjoy working in fancy Bel Air!

Can anyone deliver anonymously to my Mailbox?

No, Not really; There are no open mail slots on our PhillyBoxes, so any and all deliveries will have to be presented to PhillyBox Management during business hours to be included in that days disbursements. We have several cameras constantly monitoring the area, so 'anonymous' might not mean 'unidentifiable'...

Can't anyone just make a copy of my mailbox key?

Our PhillyBox keys are not duplicatable by your local locksmith, as it's a "reserved keyway" and additional keys must be ordered directly from the manufacturer using the key code on your original keys. They cost 4-5x more than usual blanks and they take weeks to replace (even for us!).

How do I send Virtual Snail Mail with PhillyBox?

If you're already a PhillyBox holder, subscribing to our Open & Scan Services, you can send an email to us, with the subject: Virtual Mailbox. The sending/mailing address (where the letter is addressed to) must be the only text content of the email, and the printed correspondence must be an attached PDF file to that same email. Instructions on number of copies and color preferences can be included below the address. Our plain envelope will have your PhillyBox address as the return address, and be stamped with a single Forever Stamp. Total package weight cannot exceed 1 ounce. We will respond to the email with a USPS tracking number of the resulting envelope for your records.

My mailbox can't fit all my incoming packages!

We will leave a notification in your mailbox informing you of this! The mailbox door opening is 9.25" x 10.75". Any package measuring larger than that will be automatically considered 'Oversize' and be stored securely indoors for pickup, as well as be subject to storage costs. Ring Suite A doorbell during business hours (M-F 12-6p) for PhillyBox Management.
