custom field for unique number

[Anonymous]

Hello. This is Jun Sasaki @i-enter in Tokyo,Japan.

Can I ask you there are some people who create new field in which

they can put a unique numble automatically?

We need a unique number to manage the leads perticipating in each seminar.

Thank you for your answer.The Nation Talks​​

Yes, this is definitely possible to do and I have done it on occasion.  You have to populate the value though, Marketo cannot do that automatically.

Every Marketo lead already has 2 unique numbers already assigned, and 3 unique fields total:

• the Lead ID is a unique integer
• the Marketo Unique Code is a unique alphanumeric field that is also a 64-bit integer in Base36: BE2FNKN = 24795221783
• the Marketo Unique Name is a unique alphanumeric field derived from the lead's name; it's not representable as a number, however

None of these will change over the lifetime of the lead, so if you simply need a way of referring to the lead in some outside context, it's already there.  As Jamie points out you can also create additional fields and make them unique (perhaps generating a GUID before importing a list) but Marketo will not make them unique for you.

As usual, great answers by Jamie and Sanford.

Simply if you want to show registered id for a visitor for each seminar, i recommend to use {{campaign.id}}{{lead.id}} combination.

For example

You make SC when the lead visits a registered page, SC saves {{campaign.id}}  to the custom field at flow step.

Of course you can send a unique id in the registered mail and the alert mail.
