when i submit the free trail ,the system prompt:You're not eligible for an Azure free account.But my credit card has been charged

Hi @connie mei , sorry you ran into that roadblock. Here’s what’s likely happening and what you can check:

1. Free-trial eligibility • Azure only lets each person (and each payment method) use the free account offer one time. • If you’ve ever had an Azure free account, tried a Visual Studio subscriber benefit, or used the same credit card on someone else’s free trial, you’ll see “You’re not eligible for an Azure free account.”
2. The “charge” on your card • During signup, Azure places a small, temporary authorization hold on your card (typically $1 or less) just to verify it’s valid. • That hold isn’t an actual charge and should drop off your statement within 3–7 business days. If it’s still showing as a final charge after that window, you can reach out to your bank or file a support request.

What you can try next:

• Double-check you haven’t used that card or your personal details on an Azure free trial before.
• If you’re certain you haven’t, let us know: • Which country/region you’re signing up from • The type of card you’re using (Visa, MasterCard, etc.) • The exact amount and date of the transaction on your statement

With that info we can dig in deeper or help you open a support case to clear the hold.

Hope that clears things up!

The message “You’re not eligible for an Azure free account” usually appears when there has already been an Azure subscription in the past with the same identity, or when the account details don’t meet the free-trial eligibility rules. In that case, the free trial can’t be activated and only a pay-as-you-go subscription is available.

Charges on the credit card can occur in these situations from the provided context:

1. A service that isn’t free (or a non‑free tier) was used
   • Only specific services and tiers are included in the Azure free account. If a non‑free service or tier is created or used, normal pay‑as‑you‑go rates apply, even if free credits are available.
   • After upgrading or using a non‑free subscription, usage beyond free limits is billed at pay‑as‑you‑go rates.
   • Details on which services and tiers are free are in the Azure free account FAQ linked from the documentation.
2. Usage exceeded free limits
   • Free services have monthly limits. If usage exceeds those limits, the excess is billed at pay‑as‑you‑go rates.
   • Free quantities do not roll over to the next month.
3. Sponsorship or credits do not cover all services
   • Even when credits or sponsorships exist, some services or tiers may not be covered, and those are billed to the credit card.
4. General Microsoft billing (outside Azure)
   • Some charges may be from other Microsoft subscriptions or purchases (for example, Microsoft 365, app purchases, or other services) rather than the Azure free trial itself.

To investigate and resolve the charge:

1. Check Azure subscription and usage
   • Sign in to the Azure portal and open Subscriptions.
   • Review which subscription was created (for example, pay‑as‑you‑go) and check the Overview and cost management views to see what services were provisioned and billed.
   • Use the cost management views to report on and analyze costs and verify whether any non‑free services or over‑limit usage occurred.
2. Check free‑service usage
   • Use the Azure portal to check usage of any free services and see whether limits were exceeded. Note that usage data can be delayed by 1–2 days.
3. Investigate the specific charge from Microsoft
   • Go to the Manage your payments page of the Microsoft account dashboard and use the Investigate option on the unrecognized charge to see what subscription or purchase it is tied to.
4. Open a billing support request (recommended)
   • For Azure‑specific billing questions such as “why was I charged when I tried to start a free trial,” open a billing support request from the Azure portal (billing support is free). A billing engineer can review the subscription, eligibility, and exact transaction details.

If the charge is not recognized or appears fraudulent, use the Microsoft billing investigation flow to identify the charge and then request cancellation/refund where applicable.
