Pay your Greenville Utilities bill through their website, by phone, or by mail
Greenville Utilities Commission (GUC) offers three main ways to pay your electric or water bill: online through their website, by phone with a representative, or by mailing a check. The online portal is the fastest option and lets you see your balance immediately. Phone payment takes a few minutes and works if you have your account number and a debit or credit card ready. Mail works if you prefer not to use digital payment, though it takes longer to process.
Your bill arrives monthly and shows your account number, current balance, and due date in the upper right corner. You need this account number to pay by phone or online. If you have lost your bill, you can find your account number on any previous bill, or call GUC customer service at 864-467-2505 to look it up.
Key Takeaways
- Pay online at greenvilleutilities.com by logging into your account or paying as a guest with your account number and bill amount.
- Phone payments go through GUC's automated system or a live representative at 864-467-2505, and the payment posts the same business day.
- Mailed checks should be sent to the address on your bill and take 7 to 10 business days to post to your account.
- Late fees apply if payment does not arrive by the due date shown on your bill, regardless of which payment method you use.
- Setting up automatic payments through your bank or GUC's autopay option prevents missed due dates and late charges.
Paying online through the Greenville Utilities website
Go to greenvilleutilities.com and select the payment option from the homepage. You can either log into an existing account or pay as a guest. If you log in, your account balance and payment history appear automatically. If you pay as a guest, enter your account number (found on your bill) and the amount you want to pay.
The website accepts debit cards, credit cards, and electronic bank transfers (ACH). Credit card payments may carry a small processing fee, which GUC will show you before you confirm. Debit cards and ACH transfers typically have no fee. Once you submit payment, you receive a confirmation number on screen — write this down or take a screenshot for your records.
Online payments usually post to your account within one business day. If you pay after 5 p.m. on a Friday, expect the payment to show on Monday. You can check the status of your payment by logging back into your account or calling customer service.
Paying by phone with Greenville Utilities
Call 864-467-2505 to reach GUC's payment line. You can use their automated system 24 hours a day, 7 days a week, or speak to a representative during business hours (typically Monday through Friday, 8 a.m. to 5 p.m.). Have your account number and debit or credit card ready before you call.
The automated system walks you through the steps: enter your account number, listen to your balance, confirm the payment amount, and provide your card information. The system gives you a confirmation number at the end of the call. If you speak to a representative, they can answer questions about your bill or account before processing your payment.
Phone payments post the same business day if you call before 5 p.m. Payments made after hours or on weekends post the next business day. Keep your confirmation number until the payment appears on your account.
Mailing a check to Greenville Utilities
Write your account number on the check memo line. Include the payment stub from your bill if possible — it has your account number printed on it and helps GUC match the payment to your account faster. Mail your check to the address shown on your bill. Do not mail cash.
Mailed payments take 7 to 10 business days to arrive and post. GUC considers a payment on time if it is postmarked by the due date, not if it arrives by the due date. If your due date is the 15th and you mail a check on the 14th, it counts as on time even if it arrives on the 22nd — but only if the postmark shows the 14th. To be safe, mail at least one week before the due date.
If you are paying a past-due balance, include a note with your check explaining which months you are paying for. This prevents GUC from applying your payment to the wrong billing period.
Setting up automatic payments to avoid late fees
GUC offers two autopay options: pay through your bank's bill pay system, or enroll in GUC's automatic payment plan through their website. Both methods deduct your bill amount on or near your due date each month, so you never miss a payment.
To set up autopay through GUC's website, log into your account, find the autopay or recurring payment option, and enter your bank account or card information. You choose the payment date and amount. You can change or cancel autopay anytime through your account settings.
Alternatively, set up bill pay through your own bank's website or app. Most banks let you add GUC as a payee and schedule payments for specific dates. This method keeps the payment information in your bank's system rather than GUC's, which some people prefer for security reasons.
What to do if your payment is late or rejected
If your payment does not arrive by the due date, GUC charges a late fee. The amount varies but is typically a percentage of your bill or a flat fee — check your bill or call customer service for the exact amount. Late fees appear on your next bill.
If your card or bank account is declined, GUC sends a notice to the address on file. You have a grace period (usually a few days) to resubmit payment before a late fee applies. Call 864-467-2505 to confirm the reason for the rejection and try a different payment method.
If you are having trouble paying your full bill, contact GUC customer service to ask about payment plans or hardship programs. They may be able to spread your balance over several months or connect you with local assistance programs.
Finding your account number and bill information
Your account number appears in the upper right corner of your paper bill, usually above your name and address. It is also shown on any email billing statements if you have signed up for paperless billing. The account number is a series of digits unique to your property.
If you have lost all your bills, call GUC at 864-467-2505 and provide your service address (the address where you receive water or electric service). A representative can look up your account number in seconds. You can also log into your online account if you have already created one — your account number displays on the dashboard.
Frequently Asked Questions
Can I pay my Greenville Utilities bill with a credit card online?
Yes, the GUC website accepts credit cards, debit cards, and bank transfers. Credit card payments may include a processing fee that GUC shows before you confirm. Debit cards and ACH transfers typically have no fee.
How long does it take for my payment to show up after I pay online?
Online payments usually post within one business day. If you pay after 5 p.m. on a Friday, the payment appears by Monday. You can check your account balance on the GUC website to confirm the payment went through.
What happens if I mail my check after the due date?
GUC considers a mailed payment on time if the postmark date is on or before the due date, even if the check arrives later. Mail your check at least one week before the due date to be safe. If it arrives late, a late fee applies to your next bill.
Can I set up automatic payments so I do not have to remember to pay each month?
Yes. You can enroll in GUC's autopay through their website, or set up bill pay through your bank's app or website. Both methods deduct your bill automatically each month on or near your due date. You can change or cancel autopay anytime.
What should I do if my payment was rejected?
Call GUC at 864-467-2505 to find out why your payment was declined — usually an expired card, insufficient funds, or incorrect account number. You have a grace period to resubmit payment before a late fee applies. Try a different payment method if the first one does not work.
