Stamps.com Customer Service and Phone Support

The official Stamps.com customer service number appears in the verified contact block above this article. Use that Stamps.com phone number rather than a number copied from a search result, advertisement, forum, or unofficial directory.

Official Stamps.com Customer Service Number

Before you call Stamps.com, compare the number in the verified contact block with the customer support information on the official Stamps.com site. Stamps.com may display different contact details for general accounts and multi-location organizations, so choose the option that matches your account.

To verify the phone number for Stamps.com yourself:

1. Open {site}.
2. Find Customer Support or Contact Us in the site navigation or page footer.
3. Select the support option for existing customers, not sales, partnerships, or press inquiries.
4. Confirm that the displayed Stamps.com customer service number matches the verified contact block on this page.

If two official Stamps.com pages show different numbers, use the support route shown after you sign in. Account-specific support information is more likely to direct you to the appropriate team.

Customer Service Hours

The verified contact block above lists the current published operating hours and time zone for Stamps.com customer service. Check the time zone before calling because your local time may be different.

Holiday availability can change, and the official Stamps.com support information does not provide a complete standing schedule of holiday exceptions. Check the official Help Center or the support area inside your account on the day you need assistance. A notice there may identify a closure, changed availability, or another contact method.

The official Stamps.com Help Center is the best source for current availability. Do not rely on hours copied into an old directory, cached search result, or social media post.

How to Call Stamps.com

Prepare your account information before calling Stamps.com, but do not disclose your password or a complete payment-card number. A support representative may need enough information to identify the account and understand the problem.

1. Use the verified Stamps.com customer service number shown above.
2. Listen to the menu and choose the category closest to your issue, such as account access, billing, or technical help.
3. Have your account email address or username ready.
4. Write down the exact error message, when the problem occurred, and the device or browser you were using.
5. Keep any relevant transaction, shipment, or case reference available.
6. Explain the desired result in one sentence, then provide the supporting details.

If the menu does not describe your issue, select the general customer service option. The agent can determine which Stamps.com support department handles it.

Other Ways to Contact Support

Stamps.com offers official support through chat, a contact request form, and its online Help Center. Available choices can depend on whether you are signed in.

• Chat: Look for the chat icon in the Stamps.com Help Center or account dashboard. The virtual assistant can present help articles and may offer an appropriate support handoff.

• Help request form: Open the Contact Us area in the official Help Center and enter your email address, subject, and a clear description. Attach a screenshot only after hiding private information.

• Help Center: Search by the exact feature or error message. Official articles cover account management, mailing, shipping, reports, and common technical errors.

Use the support options displayed by Stamps.com rather than sending account information to an email address found elsewhere. The available form or chat route is the safer way to reach customer service Stamps.com provides.

Sign In Before Contacting Support

Open {site} and select Log In or Sign In. Signing in can reveal account-specific help options and lets Stamps.com support identify the account connected to the problem.

Depending on when and how the account was created, the sign-in screen may accept an email address or an existing username with the account password. Enter the credentials for the affected account rather than creating another account.

After signing in, open Help and look for the chat or contact choice. Do not share your password in a support form or chat conversation.

Trouble Signing In

Use the password-reset choice on the official Stamps.com sign-in screen if you cannot remember your password. The recovery flow may ask for the username and established account-verification information before sending instructions to the registered email address.

1. Select the password-reset option on the sign-in page.
2. Enter the requested account identifier.
3. Complete the verification prompts shown by Stamps.com.
4. Check the registered email account for the recovery message.
5. Follow the official message and return to the Stamps.com sign-in screen.

If the recovery message does not arrive, check spam and filtered folders and confirm that you entered the correct account identifier. If you cannot answer the verification questions, no longer control the registered email address, or do not know which email belongs to the account, contact official Stamps.com customer service. Do not repeatedly guess credentials, and do not give an unofficial service access to your email.

Avoid Unofficial Support Numbers

An official Stamps.com page uses the company name consistently, has a secure browser connection, and provides support through the site’s own Help Center or signed-in account area. Search advertisements and look-alike pages can display a misleading stampscom phone number.

• Do not trust a number merely because it appears first in search results.
• Do not install remote-access software at the request of an unexpected caller.
• Do not reveal your password, verification code, or complete payment details.
• Do not use a “stampscom customer service” listing unless you can confirm it on the official site.

If a caller pressures you to act immediately or requests unusual access, end the call. Verify the stamps.com customer service number through the official site and start a new call yourself.
