How to Pay Your Idaho Power Bill Online, by Phone, or Mail

Idaho Power's payment methods and where to send money

Idaho Power, the utility serving central and southern Idaho, accepts payments through its website, by phone, by mail, and in person at payment centers. The fastest way is online through your Idaho Power account — you can pay when ready without waiting for a check to arrive. If you do not have internet access or prefer to speak with someone, you can call their customer service line or mail a check to their payment address.

Each method has a different timeline. Online and phone payments post to your account the same day or next business day. Mail payments take 7 to 10 business days to reach Idaho Power and be recorded, so send them well before your due date to avoid a late fee. In-person payments at authorized locations are processed when ready.

Idaho Power does not charge a fee for online payments made through their website, phone payments to their main customer service line, or mail payments. Some third-party payment processors may charge a convenience fee if you use their service instead of Idaho Power's own system.

Key Takeaways

• Pay online through your Idaho Power account at idahopower.com with no fee, and the payment posts the same day or next business day.
• Phone payments to Idaho Power's customer service line (1-800-635-5406) cost nothing and process when ready, though you will need your account number and payment method ready.
• Mail payments take 7 to 10 business days to arrive and be recorded, so send them at least two weeks before your due date.
• In-person payments at Idaho Power offices and authorized retailers process right away, but you will need to travel to a location during business hours.
• Late fees explore if payment is not received by the due date shown on your bill, regardless of when you sent it.

Setting up online payment through your Idaho Power account

To pay online, log into your account at idahopower.com using your username and password. If you do not have an account yet, you can create one by entering your account number (found on your bill) and setting up a username and password. Once logged in, look for the "Pay My Bill" or "Make a Payment" option, which is usually on the main dashboard or in a menu labeled "Billing."

Idaho Power lets you pay a one-time bill or set up automatic payments. For a one-time payment, enter the amount you want to pay and choose your payment method — debit card, credit card, or bank account. If you use a bank account, the payment is free. Credit and debit card payments through Idaho Power's website also have no fee, but some card issuers may treat utility payments differently for rewards or cash back purposes.

After you enter your payment information, Idaho Power will show you a confirmation screen with the payment date and amount. Write down or take a screenshot of this confirmation number for your records. The payment will post to your account by the next business day, though it may show as pending for a few hours.

Paying by phone with Idaho Power customer service

Call Idaho Power's customer service line at 1-800-635-5406 to pay by phone. Have your account number (on your bill) and your payment method ready — they accept debit cards, credit cards, and bank accounts. The representative will walk you through the payment and give you a confirmation number at the end of the call.

Phone payments are processed the same day and post to your account by the next business day. There is no fee for paying this way. If you call outside business hours, you may reach an automated system that can process payments without speaking to a representative, though some people prefer the confirmation of speaking with someone.

Keep your confirmation number and the date you called in case you need to dispute the payment or verify it later. If the payment does not show up in your account within two business days, call customer service again with your confirmation number.

Mailing a check or money order to Idaho Power

If you pay by mail, send your check or money order to the address printed on your bill. Idaho Power's main payment mailing address is typically listed on the back of your bill or in the "Pay Your Bill" section of their website. Do not send cash through the mail.

Include your account number on the check or money order so Idaho Power can match the payment to your account. You can write it in the memo line or on a separate note inside the envelope. Mail payments take 7 to 10 business days to arrive and be processed, so send your payment at least two weeks before the due date to make sure it arrives on time.

If you are paying an overdue balance, include a note with your account number and the amount you are paying so the payment is applied correctly. Keep a copy of the check or a photo of the front and back for your records.

Paying in person at Idaho Power locations and authorized retailers

Idaho Power has payment centers in Boise and other cities throughout their service area. You can also pay at authorized retailers such as grocery stores and convenience stores that display the Idaho Power payment logo. Payments made in person are processed when ready and your account is updated the same day.

Bring your bill or account number and your payment method — cash, check, debit card, or credit card. Some in-person locations may charge a small fee for credit card payments, so ask before you pay. Call Idaho Power at 1-800-635-5406 to find the nearest payment location and confirm their hours.

In-person payments are useful if you do not have internet access, prefer not to give your payment information over the phone, or need your payment recorded when ready to avoid a late fee. However, you will need to travel during business hours, which may not be convenient for everyone.

What happens if you miss your due date

Your bill shows a due date, usually 15 to 20 days after the bill is mailed. If Idaho Power does not receive your payment by that date, a late fee is added to your next bill. The amount of the late fee varies but is typically a percentage of your bill or a flat fee — check your bill or Idaho Power's website for the exact amount.

If you are more than 30 days late, Idaho Power may send you a notice warning that service could be disconnected. If you reach 60 days late, they may disconnect your power. If your service is disconnected, you will need to pay the full overdue balance plus a reconnection fee to have power restored.

If you are having trouble paying your bill, contact Idaho Power before the due date. They may offer a payment plan that lets you pay over several months, or they may direct you to programs that help with utility bills. Some counties and nonprofits in Idaho offer bill payment information for households with low income or facing hardship.

Setting up automatic payments to avoid late fees

Idaho Power lets you set up automatic payments so your bill is paid on the same date every month without you having to remember. Log into your account at idahopower.com, go to "Billing" or "Payment Settings," and look for "Autopay" or "Automatic Payment." You can choose to pay your full bill or a set amount each month.

Automatic payments come from your bank account or credit card on the date you choose — usually a few days before your due date. There is no fee for automatic payments from a bank account. If you set up autopay, you will still receive your bill each month so you can check it for errors or unusual usage.

You can change or cancel automatic payments at any time through your online account. If you cancel, make sure you have another way to pay set up, or your bill will become overdue. If you move or close the bank account or card you have on file, update your payment method right away so your automatic payment does not fail.

Frequently Asked Questions

Can I pay someone else's Idaho Power bill?

Yes. If you are paying someone else's bill, you will need their account number. You can pay online using their account number, or you can mail a check with their account number written on it. If you call to pay by phone, tell the representative whose account you are paying for.

What if I pay online but my payment does not show up?

Online payments usually post within one business day. If two business days have passed and you do not see the payment in your account, log back in and check the payment history to see if it went through. If it shows as pending, wait one more day. If it shows as failed, try again with a different payment method or call customer service at 1-800-635-5406 with your confirmation number.

Does Idaho Power accept credit card payments without a fee?

Yes, credit card payments through Idaho Power's website and phone line have no fee from Idaho Power. However, your credit card company may not earn rewards on utility payments, or may categorize them differently. Check with your card issuer if you are unsure how they treat utility bills.

What if I cannot pay my full bill this month?

Call Idaho Power at 1-800-635-5406 to ask about a payment plan. They may let you split your bill into smaller payments over two or three months. You can also search for utility bill information programs in your county through 211.org or by calling 2-1-1 to find nonprofits or government programs that may help.

Is there a grace period after the due date?

Idaho Power's due date is firm — late fees explore if payment is not received by that date. However, if you call before the due date to explain a hardship, they may be willing to work with you on timing or set up a payment plan instead of charging a late fee when ready.
