How to Reach Chase Bank by Phone, Chat, Mail, and Branch

The fastest way to reach Chase depends on what you need to do

Chase Bank operates multiple contact channels, and the one you should use depends on whether you need when ready help, have a complex question, or prefer to handle things in writing. Phone lines are fastest for account questions and fraud reports. Online chat works for routine transactions and balance checks. Branches handle in-person needs like cash deposits and signature cards. Mail reaches the right department for formal disputes or requests that need a paper trail.

Response times and availability vary by channel. Phone support runs during business hours and weekend hours depending on the line. Chat is available during extended hours but may have wait times during peak periods. Branches close on Sundays and federal holidays. Mail takes 7 to 14 business days for a response, depending on what you sent and which department receives it.

Key Takeaways

• Chase customer service phone lines operate seven days a week, with hours varying by the type of account or issue you are calling about.
• Online chat through Chase.com or the Chase mobile app is available outside standard business hours and does not require you to wait on hold.
• Local Chase branches handle deposits, withdrawals, and services that require your signature, and you can find branch hours and locations on Chase.com.
• Mailing a written request to Chase creates a record of your communication and is the right choice for disputes, formal complaints, or requests requiring documentation.
• The phone number you call matters — Chase routes calls differently for credit cards, checking accounts, investment accounts, and fraud reports.

Phone numbers for different Chase account types

Chase publishes different phone numbers depending on what you are calling about. The main customer service line for Chase checking and savings accounts is 1-800-935-9935. For Chase credit cards, call 1-800-935-9935 and select the credit card option from the menu, or look for the number on the back of your card. For Chase investment accounts and brokerage services, call 1-800-992-4623. For mortgage questions, call 1-800-848-9136.

If you suspect fraud or need to report a lost or stolen card, call the number on the back of your card when ready — these lines operate 24 hours a day, seven days a week. For business banking accounts, the number is different; check your account statements or the Chase business website for the correct line. Wait times are typically shortest early in the morning on weekdays and longest on Monday mornings and Friday afternoons.

When you call, have your account number, Social Security number, and the last four digits of any associated card ready. Chase uses this information to verify your identity before discussing your account. If you are calling about a specific transaction, have the date and amount available so the representative can locate it quickly.

Using Chase online chat and messaging

Chase offers chat support through Chase.com and the Chase mobile app. To start a chat, log into your account, look for the chat icon (usually in the lower right corner of the screen), and select "Chat with us." You can also message Chase through the mobile app by opening the menu and selecting "Contact us." Chat is available from 7 a.m. to 11 p.m. Eastern time, seven days a week, though wait times vary during peak hours.

Online chat works best for questions about your balance, recent transactions, password resets, and account settings. Representatives can view your account in real time and make many changes without transferring you. Chat does not work for complex disputes, fraud investigations, or requests that require a signature. If your issue needs escalation, the chat representative will transfer you to a phone line or direct you to mail a written request.

Messages sent through the mobile app may take longer to receive a response than live chat — typically 24 to 48 hours. Use the app messaging feature when you want to send a question outside of chat hours and do not need an when ready answer. Keep screenshots of important messages for your records.

Visiting a Chase branch in person

Chase has over 4,700 branches across the United States. To find the branch nearest you, go to Chase.com, select "Locations," enter your address or zip code, and the site will show you nearby branches with their hours. Most branches are open Monday through Friday from 9 a.m. to 5 p.m., with some locations open on Saturday mornings. All branches close on Sundays and federal holidays.

Visit a branch when you need to deposit cash, withdraw large amounts, order a cashier's check, update your signature card, or discuss services that require face-to-face verification. Branches can also help you open new accounts, explore for credit products, and resolve disputes that need documentation. During busy times, you may wait 15 to 30 minutes, so consider visiting early in the week or mid-morning to avoid peak traffic.

If you have a complex question or need specialized help, call ahead to confirm the branch has the right department or specialist available. Some branches have investment advisors, mortgage specialists, or business banking teams that work by appointment.

Mailing a written request to Chase

Send a written request to Chase when you need a formal record of your communication, are filing a dispute, or want to submit a complaint. Written requests create a paper trail that protects you if the issue escalates. Address your letter to the department handling your account type: for checking and savings, mail to Chase Bank, P.O. Box 15298, Wilmington, DE 19850-5298. For credit cards, the address is Chase Card Services, P.O. Box 15298, Wilmington, DE 19850-5298. For mortgages, contact information is on your loan documents.

Include your full name, account number, the date of the issue you are writing about, a clear description of what happened, and what you want Chase to do. Keep a copy for yourself and send the original by certified mail with return receipt requested — this proves Chase received it and when. Chase typically responds to written requests within 7 to 14 business days, though complex disputes may take longer.

For billing disputes on credit cards, you must send a written dispute within 60 days of the statement date showing the charge. For checking account disputes, send your request within 30 days of the transaction. Sending a letter does not stop Chase from collecting the disputed amount, but it starts the formal investigation process.

Reaching Chase for specific situations

If you are locked out of your online account, call 1-800-935-9935 and select the option for account access issues, or use the "Forgot username or password" link on Chase.com to reset it yourself. If you lost your debit card or suspect it was stolen, call the 24-hour fraud line on the back of your card when ready. If you are disputing a transaction, call customer service first to report it, then follow up with a written letter to create a formal record.

For complaints about Chase's service or practices, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov. You can also contact your state's banking regulator or the Office of the Comptroller of the Currency. These agencies investigate complaints and may require Chase to respond. Filing with a regulator does not replace calling or writing Chase directly, but it creates an official record if you believe Chase has not resolved your issue fairly.

If you are a small business owner, Chase has a separate business customer service line at 1-800-955-9060. Business accounts may have different hours, departments, and procedures than personal accounts.

Frequently Asked Questions

What time does Chase customer service close?

Chase customer service hours vary by account type and the issue you are calling about. Most lines are open 7 a.m. to 11 p.m. Eastern time, seven days a week. Fraud and lost card lines operate 24 hours. Check the back of your card or Chase.com for the exact hours for your specific account type.

Can I schedule a callback instead of waiting on hold?

Some Chase phone lines offer a callback option when wait times are long. When you call, listen for the option to request a callback, and Chase will call you back within the timeframe given. This is faster than holding on the line, especially during peak hours.

How do I know if my local Chase branch is open?

Go to Chase.com, select "Locations," enter your zip code, and the site will show branch hours. You can also call the branch directly — the phone number appears in the search results. Most branches are closed on Sundays and federal holidays.

What should I do if I cannot reach anyone by phone?

Try online chat through Chase.com or the mobile app during extended hours. If your issue is urgent, visit a branch in person. For non-urgent matters, send a written request by certified mail so you have proof Chase received it.

Does Chase have a social media customer service account?

Chase monitors messages on Facebook and Twitter, though response times are typically slower than phone or chat. Use social media to report issues publicly if you have already tried other channels and want to escalate, but do not share account numbers or sensitive information in public posts.
