Is Stamps.com legit?
LegitStamps.com is a genuine service that prints USPS postage from a home printer and now belongs to the group behind ShipStation; the sting is in the subscription. The free trial rolls into a monthly plan that bills whether or not you print anything, and the fee comes on top of the postage itself.
What we checked
- Company since 1996
- USPS-approved postage vendor since 1999
- Owned by Thoma Bravo since 2021
- Ratings on other review websites: 3.5/5
Watch out for
- A plan that keeps billing after you stopped using it, because it ends only when cancelled by phone or in the app.
- A charge on your card you did not approve, or account activity you do not recognise.
Still billed by Stamps.com after cancelling?
We help you write it, it gets its own public page, and you can have it sent to Stamps.com as a formal letter.

How do I contact Stamps.com customer service?
The Stamps.com customer support number for consumers and small businesses is 855-889-7867, and the support email is support@stamps.com. Stamps.com also runs a help center with chat, linked from the contact page shown in the contact details at the top of this page. Have your account username, the plan you are on and the dates of the charges in question ready, and note the name of the agent and the reference of every call or chat.
Trial rolled into a monthly charge you did not want? Start your complaint here alongside the call: we push it out to Stamps.com by email, social media and printed letters.
How do I cancel my Stamps.com subscription?
Stamps.com says its plans can be cancelled by phone or from inside the app, and that there is no long-term contract: the service bills monthly after a 30-day trial, so a plan that is not cancelled before the trial ends becomes a paid subscription. Cancel from the app or by calling, ask for written confirmation, and keep the date and the reference of the call. Any postage funds still on the account are separate from the subscription fee, so note that balance before you close the account and ask how it is returned.
Charged after the cancellation date? Report it here with the statement lines and the confirmation: our trained AI opens a case for you and keeps coaching you on what to reply and when to push again.
Can I report Stamps.com to my state attorney general?
Yes. In the US, the consumer protection office or attorney general in your own state takes complaints about a company's products or services, whether bought in a store or from a website, and that covers a postage subscription service such as Stamps.com. The office generally expects Stamps.com to have had a chance to put things right first, so keep a record of every call, chat and email about the charge.
Subscription charge you dispute? Put it through our complaint process and we help you write it in minutes, drawing on thousands of complaint letters that actually worked.
What do people complain about most at Stamps.com?
Nothing has been reported about Stamps.com here yet. Our research shows what typically goes wrong at online postage subscription services: a trial that converts into a monthly plan before the customer meant it to, charges that continue after a cancellation request, a cancellation that cannot be done by email, prepaid postage that is slow to come back when an account closes, misprinted or unused labels that are slow to be refunded, and software that loses the printer or the scale at the busiest moment.
Recognise the monthly charge you thought had stopped? Be the first to report it: your case opens the record the next postage customer will check before they start a trial.
What happens after I submit my complaint?
Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of Stamps.com through emails, social media, paper complaint letters and other tools at our disposal.
And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.
Can other consumers help me with my Stamps.com complaint?
Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Stamps.com can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
