public class SocialSecurityNumberClaimsPrincipalContributor : IAbpClaimsPrincipalContributor, ITransientDependency
{
    public async Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
    {
        var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
        var userId = identity?.FindUserId();
        if (userId.HasValue)
        {
            var userService = context.ServiceProvider.GetRequiredService<IUserService>(); //Your custom service
            var socialSecurityNumber = await userService.GetSocialSecurityNumberAsync(userId.Value);
            if (socialSecurityNumber != null)
            {
                identity.AddOrReplace(new Claim("SocialSecurityNumber", socialSecurityNumber));
            }
        }
