ADP is a payroll and human capital management company.
If you are an employee whose company uses ADP, the correct first contact is often your employer’s payroll or HR administrator. ADP explains that employers control registration codes, certain login credentials, payroll data, and W-2 corrections, so ADP cannot directly resolve every employee request. For general login and product-support routing, customers can call 1-844-227-5237.
Business clients should use the service-center contact information associated with their ADP product or call 1-844-227-5237 if they do not know which service center to contact. Prospective customers can speak with sales at 1-800-225-5237. Retirement participants, Wisely customers, and other specialized users should use their dedicated numbers because those teams handle different account systems.

Customers filing a complaint against ADP should first identify whether the issue involves payroll, tax filing, benefits, retirement services, a paycard, login access, employment records, HR administration, or another ADP product. Because ADP works through employers and business clients, employees often need to involve their employer’s HR or payroll department before ADP can make account-level changes. Keep pay statements, tax forms, screenshots, dates, case numbers, and previous communications before escalating a complaint.
If you are an employee, begin by contacting your employer’s payroll or HR administrator, particularly for pay errors, W-2 corrections, direct-deposit information, registration codes, or account-access issues. ADP states that it cannot directly change some employee information because the employer controls the underlying payroll account. If you are an ADP business client, contact your assigned ADP service team. Document the issue clearly and save the names, dates, and case numbers associated with each conversation.
If additional help is required, call 1-844-227-5237, ADP’s Product Login and Support Help Center. Explain which ADP product is involved, such as RUN, Workforce Now, TotalSource, retirement services, or another platform. Provide the relevant employer, client, account, or case information without disclosing passwords or unnecessary sensitive credentials. Ask whether the matter can be escalated to the correct service center or specialist. Keep the case number and notes from the call.
For complaints involving specialized products, contact the dedicated team rather than continuing through general support. Retirement participants can use 1-800-695-7526, Wisely customers can call 866-313-6901, and Global Cash Card customers can use 888-220-4477. If the complaint involves an employer’s payroll or benefits configuration, continue coordinating with the employer because ADP may require instructions from the business client. Keep all statements, screenshots, emails, and support records together.
For a serious unresolved corporate matter, written correspondence can be directed to Automatic Data Processing, Inc., One ADP Boulevard, Roseland, NJ 07068. Include your full contact information, employer or client information where appropriate, relevant product name, case numbers, dates, and a chronological description of the issue. Clearly state the resolution you are requesting and include copies rather than originals of supporting documents. Do not include passwords, complete bank credentials, or unnecessary Social Security information. Keep a copy of the complaint and proof of delivery.
If the complaint remains unresolved, the correct external process depends on the issue. Wage and payroll disputes may involve a state labor agency or the U.S. Department of Labor, tax matters may involve the IRS or relevant tax authority, retirement-plan concerns can involve applicable employee-benefit regulators, and financial or paycard issues may fall under different banking or consumer-protection agencies. The employer may also remain legally responsible for certain payroll and employment matters even when ADP processes the transaction. Keep all payroll records, tax documents, account statements, support cases, and written responses before escalating externally.
