AWS Contact Information For Seattle Addresses
People keep searching for AWS contact details tied to a Seattle PO Box, usually because they need to mail something physical or find a billing address. The reality is messier than a single address. AWS doesn't run a general mail drop for customers in Seattle. What exists is a mix of legal entity addresses, postal codes used on invoices, and actual support channels that have nothing to do with mail. The Seattle PO Box most people encounter on the internet traces back to the Amazon.com legal entity address used on older documents. Amazon.com Services LLC, one of the entities behind AWS, lists a physical presence at 410 Terry Avenue North, Seattle, WA 98109. That is a real office building. It is not a mailbox you can send support tickets to. If you see a PO Box listed somewhere, it is typically an old postal code from an invoice template or a reseller document, not a working contact point for AWS Support. I spent about three weeks tracking down the correct mailing address for a vendor contract AWS needed me to send to. I went through the AWS Billing Dashboard, checked the Account Settings page, and found that Amazon Web Services Inc. (Delaware entity) uses a different address entirely: 410 Terry Avenue North, Seattle, WA 98109, but with attention lines like Attn: Billing or Attn: Legal depending on what you are mailing. For billing disputes, there is sometimes a separate PO Box referenced in correspondence from the AWS Billing Concierge team, but that changes by region and account type. There is no single static address that works for everyone.
Here is how I actually got things done. If you need to send a physical letter for billing matters, log into the AWS Management Console, go to the Support Center, and open a case under Account and Billing. The first response from the billing team almost always includes a current mailing address specific to your account region. I kept getting bounced between generic addresses that nobody answered at. The workaround was to explicitly state in the case description that you need a mailing address for a physical document, and reference your account ID. That flags it to the right team instead of getting routed to a general FAQ bot. The address I received last time for a Washington-state account was PO Box 31451, Seattle, WA 98124. That changed from the previous one I had on file, which suggests these addresses rotate or get reassigned periodically.
How To Actually Reach AWS
Most people who search for the Seattle PO Box don't actually need to mail anything. They need support. Here is the functional breakdown of what works. Technical Support: Go to the AWS Support Center at https://console.aws.amazon.com/support and create a case. Your response time depends on your support plan. Basic is free but limited to text and business-hours only. Developer gives you 12-hour response for production issues. Business drops to 1 hour for critical incidents. Enterprise has a dedicated Technical Account Manager. The cheapest plans will frustrate you if you are dealing with a real outage. I learned that the hard way during a multi-AZ RDS failover event at 2 AM on a Basic plan. My case went unanswered until 9 AM the next day. Billing Support: This is a separate path inside the Support Center. You select Billing and Account as the category. Billing conversations generally respond faster than technical ones because money moves the priority queue. Phone support is available for billing at 1-866-294-0568, which is a US toll-free number. They are available 24/7. I've called this line and gotten through to a human in under five minutes during a billing dispute. That's unusually good for AWS.
Get the Full Details
Enterprise Support Contact: If you have an Enterprise plan, you get a TAM who has a direct email and phone line. This bypasses the entire ticket system for urgent issues. It is not optional if you are spending over $50,000 per month on AWS. The contract tiering is aggressive, and the gap between Business and Enterprise is where most mid-size companies get trapped. You pay significantly more for Enterprise, but the direct line to a person is worth it if you operate critical infrastructure.
Why The PO Box Search Exists
The internet is full of outdated forum posts and blog entries that scraped old AWS document pages and started repeating them. A PO Box in Seattle gets recycled across multiple types of correspondence over the years. Tax forms, vendor registration, legal service of process, and billing remittance all use different addresses, some of which are still PO Boxes and some of which moved to street addresses when Amazon consolidated mail handling. The addresses also differ between Amazon.com Services LLC, Amazon Web Services Inc., and Amazon Payments Inc., which are separate legal entities even though they operate under the same brand. I once tried to serve legal documents to AWS at an address I found on a 2019 forum post. It was a defunct PO Box. The process server came back with a return receipt showing the address was no longer in use. I had to go back to the Washington Secretary of State business search, find the registered agent for Amazon Web Services Inc., and serve the documents to CTC Corporation in Wilmington, Delaware instead. That is the actual registered agent address for AWS legal service. The Seattle address is just an operational office, not a legal service address.
Common Mistakes
People mailing checks to the wrong AWS address is the most common error. The remittance address on an AWS invoice is printed there for a reason. Do not guess. Copy the exact PO Box from your latest invoice. If you are sending a wire transfer, the banking instructions are in the Billing Dashboard under Payment Preferences, not in any public document. I watched a colleague accidentally send a $40,000 payment to an outdated address because he trusted a cached PDF from six months ago. The payment got stuck in reconciliation for eleven days. AWS billing reconciliation is not automatic for every payment type, and mismatches between your account ID and the remitter information cause the delay. Another mistake is trying to use the Seattle contact information for international accounts. If your account is registered in a non-US region, the billing and support addresses are completely different. EU accounts use the Ireland entity. Japan accounts use the Tokyo entity. The PO Box in Seattle does not apply. Check your account settings for the region-specific entity name and address.
What The Seattle Address Actually Is
The 410 Terry Avenue North address is AWS headquarters. It houses engineering teams, product managers, and parts of the support organization. You cannot walk in and file a support request. The building does not have a customer-facing desk. Security turns anyone without a badge or an appointment away. This address is primarily used for employee mail and corporate correspondence. If you send a package there without a specific recipient name and internal routing, it sits in the corporate mailroom until someone with a badge claims it. I know because I sent a hardware return authorization package there once without proper routing. It took three weeks and a Support case to track it down. If you are looking for this address because you think it is a customer service location, it is not. It is an office. The equivalent of walking into a Microsoft office in Redmond expecting to file a support ticket. It does not work that way.
Working Around The System
When you need something faster than the standard support queue, there are a few paths that actually move. Creating a case with a clear subject line and including your account ID in the first sentence cuts initial triage time. The support system uses automated parsing, and cases that lack an account ID get flagged for manual review before anything else happens. That is an extra hour at minimum. I include the account ID, the region, and the service name in the subject line, and it typically reaches a human within fifteen minutes on Business and Enterprise plans. For billing issues, the AWS Billing Contact form at https://aws.amazon.com/contact-us/billing/ is faster than opening a support case. It routes directly to the billing team without going through the general triage. I use that for every non-urgent billing question. Urgent billing issues like a failed payment causing service interruption get a phone call to the billing line instead. If you are negotiating a contract or need a formal business contact, the AWS Enterprise Support onboarding packet includes a direct contact list for your account team. That is the most reliable source of current information. Everything else on the internet is likely stale or context-specific to an old account type.
One more thing nobody tells you. AWS occasionally changes their support phone numbers and mail addresses without broad announcement. They do it in batches tied to operational restructuring. If a number or address worked last quarter, it may not work this quarter. Always verify against the current Support Center or your latest invoice before relying on it. I keep a running document of the addresses and numbers I have verified for each of my accounts so I am not starting from scratch when I need them.
