Finding Internal IDs of Records
In NetSuite, each record is assigned an internal ID when it is created. If the Show Internal IDs preference box is checked, an Internal ID column is shown when viewing record lists.
For example, to see the internal IDs of customer records, go to Lists > Relationships > Customers (Administrator). The internal ID of each record in the customer record list is found under the Internal ID column (see the following screenshot).
When the Show Internal IDs preference is cleared, or if the internal IDs aren't shown on a particular page within NetSuite, you can see the record's internal ID by hovering over a link to that record. The internal ID is shown as a parameter in the URL in the browser status bar.
The following screenshot shows that if you hover over a link to the ABC Co. customer record, the internal record ID (1766) appears in the browser status bar.
You can also get the internal ID of a record type (for example, ‘salesorder’) by going to the SuiteScript Records Browser. For information about using the SuiteScript Records Browser, see Working with the SuiteScript Records Browser in the NetSuite Help Center.
