CenturyLink Promo Codes & Coupons September 2025

If your CenturyLink promo code isn’t working, it’s usually due to code expiration, eligibility restrictions, or input errors. Common error messages include “Invalid code,” “Code expired,” or “This offer is not available for your order.”

CenturyLink promo codes often have strict terms, such as being valid only for new customers, specific service tiers, or select products. Many codes are single-use, meaning they can’t be reused once redeemed. Other frequent issues include:

• Entering the code incorrectly (case sensitivity matters)
• Trying to use a code on ineligible items or services
• Attempting to stack codes (CenturyLink rarely allows this)
• Using a code after its expiration date

To resolve the issue:

1. Double-check the code for typos and ensure it matches the offer.
2. Review the code’s terms—some are only for first-time customers or specific plans.
3. Make sure your cart meets any minimum requirements.
4. If you see “Code expired,” look for a new, active code on trusted coupon sites with live success tracking.

Pro tip: Always copy and paste codes directly from a verified source and check real-time success rates before applying at checkout for the best chance of success.

No, CenturyLink does not allow customers to combine multiple promo codes or discounts on a single internet plan purchase. The checkout system will only accept one code per order, and you’ll typically see an error like “Only one promo code can be applied per transaction” if you try to stack offers.

This restriction is standard for CenturyLink and is often stated in the terms of most codes, which often read “Cannot be combined with other discounts”. This applies to both percentage-off and dollar-off codes, as well as special offers like free months or bundled services.

If you have several codes, choose the one that offers the greatest savings for your specific order. Some codes are limited to certain products or customer types, so read the fine print before applying.

Pro tip: Compare all available codes and select the one with the highest value for your plan—using a reputable coupon aggregator with live tracking can help you spot the best deal quickly.

Most CenturyLink promo codes are targeted at new customers or first-time purchases, but there are occasional offers for existing customers, such as discounts on upgrades, add-ons, or business services. However, these are less common and usually have more restrictions.

For example, codes like “$10 off current promotional price for 6 months” are often limited to new sign-ups or upgrades, not renewals. Existing customers may receive targeted email offers or loyalty discounts, but these are typically not the same as public promo codes.

To find offers for existing customers:

• Check your CenturyLink account dashboard for personalized deals.
• Look for codes labeled for “eligible members” or “selected services” on reputable coupon sites.
• Contact CenturyLink customer support to ask about loyalty or retention offers.

Pro tip: If you’re an existing customer, call CenturyLink’s retention department and mention competitor offers—agents sometimes have access to unpublished discounts or can apply special rates to keep your business.

CenturyLink may occasionally offer discount codes, but currently, there are none available. However, customers can still save money by taking advantage of other promotional offers or sales available on the website, or by using credit card points to make purchases.
