How to obtain a field ID
Often people ask me how to get fields IDs in order to build their custom links. I thought it would have been helpful to write a post about this. Let’s see how to get a field ID for custom and standard fields.
Custom Fields
In order to get the ID of a custom field proceed this way:
- Click on Setup, then on Customize, select the Object you desire (e.g.: Leads) and click on Fields;
- Click on the name of the custom field you previously created
- Look at your browser’s address bar, you’ll see something like:
https://emea.salesforce.com/00N20000000thpj - The 15 digit code that appears immediately after https://emea.salesforce.com/ is the ID of that custom field; in this case the ID of the custom field I selected is 00N20000000thpj
Easy enough, isnt’t it 
Standard Fields
Salesforce.com provides a list of the field’s name for its standard fields, which can be found attached to the solution “How do I create custom links?” and that I decided to paste here as a quick reference:

Thanks – this really beats searching through source!
I am trying to import Activities but I get the impression I need an ActivityID – where can I find out what these are?
@Rebecca: how about running a report on Activities including the Activities IDs?
Hi there,
How can I find the id for user fields? I am trying to create a user from a contact record and prepopulate some of the fields….
Thanks
…actually I found them. I posted them here if anyone is interested:

We are using Salesforce.com as a helpdesk application. Currently, we have to enter information in the case close window in order to close a ticket. We need to setup a button on our cases to allow us to bypass this and automatically close a case with generic information. Does anyone know of any code that will allow us to do this? I talked with Salesforce and they told me that we need to set up an S-Control, but that they can’t help me with that. I’m a novice so any help would be appreciated.
Thanks!
the type field on activities is tsk10 much like the event type field evt10
Hi
We have a custom field in Sales Force and a have a simple web-to-lead form on our website that uses ringlead to pass the lead to Sales Force.
The Custom ID and Name that Sales Force gave us for inclusion on this form (to be attached to the ‘region’ field) is:
0N30000000mnNj
This is a nightmare for clientside javacript/ajax validation as
IT IS NOT WEB COMPLIENT – name an id should not begin with a digit, should begin only with a letter. please see W3 ‘s website:
http://www.w3.org/TR/html401/types.html#type-id
This is a serious problem as I am unable to write ANY JavaScript validation for this field and subsequently data is lost and leads are not being distributed correctly which is harming our business. Why could sales force not spot this and is there a way to customise this custom field name and id so that at least it starts with a letter???
Has anyone come against this issue and found a work-around in JavaScript validation???
Thanks
@Steve: Thanks for pointing this out; I believe the forms will post the values to Salesforce if only the NAME attribute contains the actual Id of the field; this shouldn’t prevent you from changing the value of the ID attribute to something more comprehensible (eg: “region”) and validate the field via Javascript using something like: getElementByID(“region”).
Please let us know if this helps (works).
[...] Most standard and custom fields on any object can be pre-filled using a URL parameter. You just need to figure out the corresponding parameter name. In this case, the parameter opp3 corresponds with the Opportunity Name field. Here’s a good post that provides the instructions and a complete list: Decoding Salesforce. [...]
Hi there – minor correction – the Status field is actually tsk12 not tsk4
I can’t get custom lookup fields to populate with data using this method, am I missing something?
Thanks!!!
Is there any way to programmatically get at this ID from the API? I need to get a list of Field Name & Field ID. Having to manually hover and copy past the Field ID from the URL just doesn’t seem right.
Thanks for the info here. It helped jump start my first efforts at a custom button…I am setting several field values successfully. However, I can not seem to figure out how to set the “Reminder” checkbox to ‘empty’ (false, 0, whatever). Nor can I locate that fieldID…. any help?
Jay
An easier way to get all of your ID numbers from Salesforce is to generate a web to lead form in the setup control panel. Just make sure that you create a web to lead form with all of your fields.
Salesforce will then generate an HTML file with a form that has the names and ID numbers for every field in your account.
I’m trying to use a custom URL button to change a record type. How do i find the Field ID for RecordTypeID on the account?
Hi! I was surfing and found your blog post… nice! I love your blog.
Cheers! Sandra. R.
What about code for custom objects?
What are the field names for Lead Owner, Account Owner, and Contact Owner? Anyone been able to hack this? I know Owner ID, but formulas like OwnerId . Email return a syntax error that OwnerId that field (OwnerId) does not exist.
