Instructions

Software Usage Instructions

Set generation quantity:Select the number of OAIDs to generate. Batch generation of 1-50000 entries is supported, with preset quantities or custom input available. When exceeding 1000 entries, the system automatically processes them in chunks and displays a progress bar to avoid page lag.
Select device manufacturers:
- Supports 18 mainstream manufacturers: Huawei, Honor, Xiaomi, Redmi, VIVO, iQOO, OPPO, OnePlus, Realme, Samsung, Lenovo, ASUS, Meizu, Nubia, ZTE, Google, Motorola, and Sony
- Multiple manufacturers can be selected, and you can also use the "Select All", "Popular", and "Clear" shortcut buttons
- Supports the "Proportional allocation" mode, allowing you to set a generation ratio for each manufacturer (such as Huawei 30%, Xiaomi 20%) to precisely control data distribution
- Supports custom prefixes (1-8 hexadecimal digits) to simulate OAIDs for specific manufacturers or specific rules
Select system versions:Supports Android 10-16 versions. Multiple version combinations can be selected to help simulate different device environments.
Select regions:Supports region codes such as CN (Mainland China), HK (Hong Kong), TW (Taiwan), MO (Macau), SG (Singapore), MY (Malaysia), JP (Japan), KR (South Korea), and IN (India).
Configure output options:
- Ensure no duplicates:Uses secure random numbers + a deduplication algorithm to ensure the OAIDs generated this time are not duplicated
- Include device information:Displays information such as manufacturer, model, Android version, and region in the results
- Output generation time:Attaches a generation timestamp to each result for archiving and traceability
- Save history:Automatically saves the most recent 20 generation configurations and result summaries, with one-click restore supported
- OAID format:Supports standard format (32 lowercase characters), grouped format (8-4-4-4-12), uppercase format, and lowercase format
- OAID version:Supports two versions: v1 (standard 32-digit hexadecimal) and v2 (with check digit)
- Download format:Supports export in four formats: TXT, CSV, JSON, and Excel
Start generation:Click the "Start Generation" button or use the Ctrl+G shortcut. The system will batch-generate OAIDs based on the current settings and display progress in real time.
View statistics:After generation is complete, you can view the generated quantity, unique quantity, number of skipped duplicates, generation time, and distribution statistics for each manufacturer.
Copy and download:You can choose "OAID only" or "With device information" to copy (shortcut Ctrl+Shift+C), or download as a TXT, CSV, JSON, or Excel file.
Validation and cleaning:Switch to the "Validation and Cleaning" tab. Paste or drag and drop TXT/CSV files to import them. The system automatically checks format validity, removes duplicates, identifies manufacturer sources, and allows you to copy or download the valid list. Invalid rows are listed separately with details.
List comparison:Switch to the "List Comparison" tab, enter two OAID lists, and calculate the intersection (common), difference (unique), and union with one click, making it easy to compare data from different batches or sources.
History:Switch to the "History" tab to view the most recent 20 generation records. You can restore historical configurations with one click to regenerate, or delete individual records or clear all history.

FAQ

A: OAID (Open Anonymous Device Identifier) is an open anonymous device identifier introduced by the Mobile Security Alliance (MSA), mainly used for ad attribution, app analytics, and development testing. Compared with IMEI, OAID places greater emphasis on privacy protection and can be actively reset by users. It is suitable as a replacement for traditional unique hardware identifiers in Android 10+ environments and is the ad tracking solution recommended by mainstream manufacturers in China.

A: It currently supports 18 mainstream manufacturers: Huawei, Honor, Xiaomi, Redmi, VIVO, iQOO, OPPO, OnePlus, Realme, Samsung, Lenovo, ASUS, Meizu, Nubia, ZTE, Google, Motorola, and Sony. Device model data has been updated to the latest 2025-2026 models. You can generate results by selecting one manufacturer, multiple manufacturers, or a proportional mix.

A: They are suitable for scenarios such as mobile app development testing, ad attribution system integration testing, data analytics platform stress testing, user behavior analysis simulation, A/B test data filling, security research, and bulk data simulation. The generated results are randomly simulated data and do not correspond to real devices.

A: A standard OAID is a 32-character hexadecimal string (v1), such as 6ac3ba5f0d4b9194d3867e2aec7f5b20. This tool also supports the v2 version (with a check digit), as well as the 8-4-4-4-12 grouped display format (similar to UUID format). The validation feature can automatically recognize both formats and check their validity.

A: After enabling proportion mode, you can set a weight value for each manufacturer (such as Huawei 30, Xiaomi 20, OPPO 10). The system will allocate the generated quantity according to the specified proportions rather than using purely random uniform distribution. This is suitable for simulating the device share distribution of different brands in the real market.

A: No. OAID generation, validation, deduplication, comparison, and export are all completed locally in your browser, and no data is uploaded to the server. History is also stored only in the current browser's localStorage and can be deleted by clearing browser data.

A: Four export formats are supported: TXT (plain text, suitable for direct copying), CSV (comma-separated, suitable for spreadsheet software such as Excel), JSON (structured data, suitable for program interfaces and automated testing), and Excel (spreadsheet format, suitable for data analysis).

A: Switch to the "List Comparison" tab, paste two sets of OAID lists into the left and right input boxes, and click "Start Comparison". The system will automatically calculate the intersection (common items), items unique to A, items unique to B, and the union of the two datasets, making it easy to compare device data differences across batches, channels, or time periods.

A: The tool uses chunked generation and asynchronous rendering technology, supporting batch generation of up to 50000 entries. If lag occurs, we recommend reducing additional information output, using the standard format, and waiting until the progress bar is complete before taking further action. When generating more than 10000 entries, it is recommended to use a modern browser such as Chrome or Edge for the best performance.

A: Ctrl+G is supported for quick generation, and Ctrl+Shift+C is supported for quickly copying results, improving batch operation efficiency.
