Square customer service can help sellers with account access, payment processing, transfers, payment holds, reserves, disputes, refunds, invoices, hardware, subscriptions, Square Banking and other business-account concerns. Square is part of Block, Inc., and most product-related problems should begin with Square Support rather than the parent company’s corporate office.
How to Contact Square Customer Service
Square’s help articles can be viewed online at any time, but that does not mean a live phone or chat representative is available 24 hours a day. Square’s Support Assistant may first provide automated help and then offer a live support representative when one is available.
Best Square Support Route by Issue
- Cannot sign in: Try Square’s password-recovery and sign-in tools. Call support if you no longer have access to the email address or phone number connected to the account.
- Payment or Point of Sale problem: Check the Square Support Center for the specific Square app, reader, register or payment method before contacting general support.
- Missing or delayed transfer: Review the Balance and Transfers sections of Square Dashboard and confirm that the linked bank account is active and verified.
- Account review or information request: Respond through Square Dashboard using the documents Square requests. Avoid sending sensitive documents to an unverified email address.
- Reserve or payment hold: Review the Reserve Dashboard and the notice Square sent to the email address associated with the account.
- Customer payment dispute: Open the Disputes section of Square Dashboard and respond before the deadline shown on the case.
- Refund problem: Confirm the refund status in Dashboard and remember that the customer’s bank may need additional time to post a completed refund.
- Square Checking card issue: Call 1-866-200-8599, especially for a lost card, unauthorized card transaction, compromised PIN or card-account concern.
- Hardware purchase or setup: Use Square Support for troubleshooting. Contact Square sales at 1-833-959-5325 for new-product purchasing questions.
- Account closure: Export payment history, customer data and tax documents before deactivating the account.
Information to Have Before Contacting Square
- The email address and phone number associated with the Square account
- Your business name and Square location name
- The date, time and amount of the affected payment or transfer
- The transaction, transfer, dispute or case number
- The last four digits of the relevant payment card or linked bank account, when requested through a secure official channel
- Copies of receipts, invoices, delivery confirmation or customer communication
- Screenshots of error messages without exposed passwords or verification codes
- The model and serial number of affected Square hardware
- Copies of prior Square messages and the name or case number from earlier support contacts
Square Login and Account Access Problems
If you cannot sign in, verify that you are using the email address or phone number originally connected to the Square account. Check spam folders for password-reset or verification messages and confirm that your phone can receive text messages.
If you no longer control the original email address or phone number, or if you received an account-change notification you did not request, contact Square by phone. Do not create multiple replacement accounts until you understand what happened to the original account, especially if it contains payment history, pending transfers, customer information or tax documents.
Square Transfers, Payment Holds and Account Reviews
A delayed transfer does not always mean the funds have been permanently withheld. First review Square Dashboard for a failed bank transfer, information request, verification notice, reserve, payment limit or account-review message.
Square may request business information or supporting documents while reviewing unusual activity or transactions. Transfers can be suspended during a review. Submit only the requested information through Square’s official Dashboard or secure support process, and save copies of everything provided.
If a reserve has been placed on the account, review the percentage being held, the release schedule and the reason shown in the Reserve Dashboard. Square describes reserves as funds set aside to help cover possible payment disputes or chargebacks. Keep records of transaction history, delivery, signed agreements, refund policies and customer communication in case Square requests additional documentation.
Square Payment Disputes and Chargebacks
When a customer disputes a Square payment through a card-issuing bank, Square generally places the disputed amount on hold while the case is reviewed. Open the dispute in Square Dashboard, review the response deadline and provide the documentation requested for that transaction.
Useful evidence may include a signed contract, itemized invoice, customer authorization, delivery confirmation, refund policy, cancellation terms, photos, service records and communications showing that the buyer received what was promised.
The card-issuing bank, not Square alone, makes the final decision in many payment disputes. Square says a bank decision may take up to 90 days in some cases. Keep sufficient funds available for unresolved disputes and watch the email address associated with the Square account for updates.
Square Refund, Invoice and Subscription Questions
For a refund complaint, confirm whether the refund was successfully submitted and whether it appears in Square Dashboard. A completed card refund may still require additional processing time before the customer’s bank posts it.
For Square Invoices, compare the invoice status, payment date, customer email address and payment method. For recurring subscriptions or paid Square software, review the subscription settings before closing the account so that an unwanted plan does not remain active.
Square Checking and Card Security
Square Checking has a separate support number at
1-866-200-8599. Use this route for a lost or stolen Square Checking card, unauthorized card activity, a compromised PIN, replacement-card questions or other Square Checking account concerns.
Report a missing or compromised card immediately. Do not post the full card number, account number, PIN or transaction details in a public review. Square Checking is a business product, and its protections and error-resolution rules may differ from those that apply to personal consumer bank accounts.
Square Customer Service Reviews and Complaints
CustomerServiceNumbers.com currently shows one visible Square review. The February 2018 reviewer gave Square a 2-out-of-5 rating and described difficulty accessing an existing Square account. The reviewer wanted direct help from a person so the account could be used to accept client payments.
One older review is not enough to establish reliable Square customer-service or complaint trends. Newer reviews can help readers understand current experiences involving account access, live support, transfers, reserves, disputes, refunds, hardware and whether Square resolved the issue.
Privacy, Payment and Scam Warnings
- Use only Squareup.com, the Square Dashboard or the official Square app when entering account, banking, tax or identity information.
- Do not give anyone your password, two-step verification code, full payment-card number, PIN, Social Security number or complete bank-account information.
- Be cautious with callers, texts or emails claiming that your Square account is frozen and demanding immediate payment, cryptocurrency, gift cards or remote access to your device.
- Square Support should not need your password or one-time verification code to provide ordinary assistance.
- Do not send identity documents or other sensitive personal information through an unverified or unencrypted email address.
- If an unauthorized change or transaction appears, contact Square immediately, secure the associated email account and update reused passwords.
- Do not post customer names, card details, tax information, bank information or confidential dispute evidence in a public review.
