Combine Amazon Order History Across Multiple Accounts
Last updated · By the TinyFlash team
Amazon won't let you merge accounts. Here's how to merge their order history. Order History Downloader detects each Amazon account on import, labels it locally, and lets you filter or export every account in one viewer — without sending an account name anywhere.
Quick facts
| Workflow | Sign A → Import → Sign B → Import → Filter |
|---|---|
| Account ID | First 12 hex of SHA-256(host + display-name) |
| Account names sent off-device | Never |
| Friendly labels editable | Yes — Options page |
| AccountFilter dropdown | Auto-populates at ≥2 accounts |
| Price | Free — no paywall on multi-account |
Key takeaways
- March 20, 2023: Amazon retired the official Order History Reports tool. Multi-account aggregation has not been a first-party feature on Amazon since.
- 12 hex characters: account detection uses the first 12 hex of
SHA-256(host + display-name)— distinguishing accounts without storing the account name itself. - ≥2 accounts: the AccountFilter dropdown auto-populates the moment a second account is imported.
- 0 paywall: multi-account partitioning is free in v1.0 — every feature shipped for everyone.
- 1 click: filter, isolate, or combine accounts in the viewer; exports honor the active filter.
Why Amazon doesn't combine order history
Amazon retired the official Order History Reports tool on March 20, 2023, and nothing first-party replaced it. Households that share a Prime plan often assume the linkage runs deeper than it does. It doesn't. Amazon Household pools certain payment methods and lets two adults split Prime benefits, yet each account keeps its own private order list. The same wall sits between an Amazon Business account and the personal account behind it, and between a parent's login and a teenager's.
That's the gap people keep running into on Amazon's help forums. Threads ask the same question different ways — combine kids and parents, merge business and personal, see a partner's purchases for the joint budget — and the official answer remains some variation of “you can't.” Order History Downloader sidesteps the missing feature entirely. Each account gets imported separately, on your device, in the same browser session you'd use to log in normally. The merging happens locally in the viewer, not on Amazon's side.
Three multi-account situations this solves
Household: partner + me
Two adults, two Prime accounts, one mortgage. Amazon Household links payments and Prime perks but keeps each person's orders private. Pull both accounts into one viewer to see what the household actually bought this year.
Business: personal + LLC
An Amazon Business account for the consultancy, a personal account for everything else. Tax season needs them separated, year-end review needs them combined. The same import flow handles both — one filter switches the view.
Parental: kids' Amazon
A teenager has their own login for school supplies, a child profile for books. Parents want oversight without rummaging through three sign-in screens. Import each, label them, and the viewer shows the whole household at once.
How Order History Downloader detects each account
The extension reads the display name Amazon already shows in its top navigation — the “Hello, [name]” string on Your Orders — and runs it through a SHA-256 hash together with the storefront host. From that, it keeps only the first 12 hex characters as the account's identifier. The full display name is discarded the moment the hash is computed. Re-imports from the same account land on the same hash, so rows never duplicate or cross over into the wrong account.
AccountHash = SHA-256(host + display-name).slice(0, 12)
// example: "amazon.com" + "Sarah B." → "a3f4d92b8c01"
// "amazon.de" + "Sarah B." → "7e2b1f48d6c5" (different host, different hash)Best-effort attribution: the hash is built from what Amazon publicly renders for you on its own page, so two different Amazons (e.g. .com and .de) yield two hashes for what you might consider one identity. That's deliberate — storefronts hold separate order histories anyway.
The merge flow, step by step
- 1
Sign into Amazon account A and import
On any of the 10 supported Amazon storefronts (.com, .co.uk, .de, .ca, .fr, .it, .es, .nl, .pl, .se), open Order History Downloader, pick a date range, and hit Import. The viewer fills with account A's orders, tagged with its 12-hex hash.
- 2
Sign out, sign into account B, import again
Switch to your second Amazon login on the same storefront — partner, business, kids' — and run the import a second time. Account B's rows join the same local viewer, tagged with a separate hash.
- 3
AccountFilter dropdown auto-populates
As soon as a second account hash is detected, the AccountFilter control appears at the top of the viewer. Pick one account to isolate it, leave it on All to see both, or check rows manually for a custom selection. CSV, Excel, and bulk-PDF exports honor whichever view is active.
- 4
Rename hashes to friendly labels
Open the extension's options page and edit the account-labels table. Rename
a3f4d92b8c01to Personal, the next hash to Business, a third to Kids — or any label you prefer. Labels persist across imports; the underlying hash never changes.
Editable friendly labels
The 12-hex hash is precise but ugly to read. The options page exposes a label table where each detected hash gets a free-text name — Personal, Business, Partner, Kids, Client A, anything that fits how you actually think about the account. Saved labels populate the AccountFilter dropdown, the per-row badges in the viewer, and the Account column in every export. Past imports stay intact if you rename — labels are display-layer only, the hash itself is the join key.
Best-effort attribution: the friendly-label table is one of the editable surfaces in the extension's options page, alongside default export format, detail-page concurrency, and the field-pref matrix.
The AccountFilter dropdown in the viewer
Verbatim from the product docs: “AccountFilter dropdown auto-populates when ≥2 accounts detected. Friendly-label table editable in the options page. Legacy rows collapse to ‘Legacy / unknown account’ without a Dexie migration.” In practice, the dropdown sits above the order table next to the date and retailer filters. One click isolates an account; clearing it folds everything back into a combined view, and the running Σ row at the bottom recalculates against whatever is currently selected. URL-hash persistence means a filtered view survives a reload or a shared link.
Privacy: what stays local, what leaves
Account names never leave your device. The hash is computed in the browser, the full display name is discarded, and the resulting 12-hex string is stored in IndexedDB alongside your imports. The TinyFlash backend has no record of which accounts you run.
The exact text from the canonical privacy policy: “Everything the extension produces is written locally on your machine. CSV, Excel (.xlsx), and PDF exports are saved through the standard Chrome download prompt, to a folder you choose. Local cache in IndexedDB, scoped per retailer account, used to resume interrupted imports and avoid re-fetching the same orders. Preferences are stored using Chrome's chrome.storage.local. They never leave your device.”
And on what does leave: “A small amount of operational metadata is sent to the TinyFlash backend so we can keep the extension working as retailers redesign their pages. No order data is included. These reports do not include cookies, IP addresses logged by us beyond short-lived load-balancing logs, account identifiers, names, emails, or order content of any kind.” The full policy lives at tinyflash.org/privacy.
Tax prep, yearly totals, and the rest of the household
Two situations push multi-account work past curiosity into requirement. Tax season, when the LLC's purchases need a clean line between deductible and not. And the once-a-year “where did the money go” review, where a household genuinely wants the partner's and the kids' spend in the same total. Both are downstream of the merge flow on this page.
For Schedule C-style splits, the Amazon order history for taxes walkthrough shows how to filter by business hash and export only that view. For a combined household view, the Amazon yearly spending report page explains how the Σ row groups currencies and how to slice spend by month once every account is in the same viewer.
What's missing from the alternatives
Order History Downloader v1.0 (May 2026) is the only Chrome Web Store extension in this category that ships multi-account partitioning out of the box. Other tools handle a single account well, then hit a wall when a second login enters the picture — either rows merge with no marker, or one account's data overwrites another's on re-import. The hash-keyed Dexie store removes both failure modes. For the broader context on why a third-party tool exists at all, the Order History Reports replacement page covers the 2023 retirement and what changed.

Frequently asked questions
Can I see Amazon orders from multiple accounts in one place?
Yes. Order History Downloader detects each account by a local-only hash and labels it in the viewer. After importing from each account, the AccountFilter dropdown lets you filter or combine accounts in one view, and exports respect whichever filter is active.
How do I track my Amazon Business and personal account together?
Sign into your personal Amazon account first and run an Order History Downloader import. Then sign into your Amazon Business account and run another import. The viewer detects two account hashes and lets you switch between them — or export both in one CSV by selecting all rows.
Does Amazon Household combine order history?
No. Amazon Household shares Prime benefits and certain payment methods between linked adults, but each account's order history stays private to that account. Order History Downloader is the bridge — it imports each account separately on your device and lets you see them together locally.
How does Order History Downloader tell my accounts apart without seeing my email?
It generates a local account identifier from the first 12 hex characters of `SHA-256(host + display-name)`. The display name is what Amazon already shows on your Your Orders page. Nothing about this hash leaves your device.
Can I label my accounts in the viewer?
Yes. Open the Order History Downloader options page and edit the friendly-label table to rename "Account #1" to Personal, Business, Partner, Kids, or any label you choose. The labels are stored locally and persist across imports.
